* Surface stacking and ordering.
*
* This is handled using several linked lists of surfaces, organised into
* layers. The layers are ordered, and each of the surfaces in one layer are
* above all of the surfaces in the layer below. The set of layers is static and
* in the following order (top-most first):
* Lock layer (only ever displayed on its own)
* Cursor layer
* Fullscreen layer
* Panel layer
* Input panel layer
* Workspace layers
* Background layer
*
* The list of layers may be manipulated to remove whole layers of surfaces from
* display. For example, when locking the screen, all layers except the lock
* layer are removed.
*
* A surfaces layer is modified on configuring the surface, in
* set_surface_type() (which is only called when the surfaces type change is
* _committed_). If a surfaces type changes (e.g. when making a window
* fullscreen) its layer changes too.
*
* In order to allow popup and transient surfaces to be correctly stacked above
* their parent surfaces, each surface tracks both its parent surface, and a
* linked list of its children. When a surfaces layer is updated, so are the
* layers of its children. Note that child surfaces are *not* the same as
* subsurfaces child/parent surfaces are purely for maintaining stacking
* order.
*
* The children_link list of siblings of a surface (i.e. those surfaces which
* have the same parent) only contains weston_surfaces which have a
* shell_surface. Stacking is not implemented for non-shell_surface
* weston_surfaces. This means that the following implication does *not* hold:
* (shsurf->parent != NULL) !wl_list_is_empty(shsurf->children_link)

Split the geometry information from weston_surface out into weston_view The weston_surface structure is split into two structures: * The weston_surface structure storres everything required for a client-side or server-side surface. This includes buffers; callbacks; backend private data; input, damage, and opaque regions; and a few other bookkeeping bits. * The weston_view structure represents an entity in the scenegraph and storres all of the geometry information. This includes clip region, alpha, position, and the transformation list as well as all of the temporary information derived from the geometry state. Because a view, and not a surface, is a scenegraph element, the view is what is placed in layers and planes. There are a few things worth noting about the surface/view split: 1. This is *not* a modification to the protocol. It is, instead, a modification to Weston's internal scenegraph to allow a single surface to exist in multiple places at a time. Clients are completely unaware of how many views to a particular surface exist. 2. A view is considered a direct child of a surface and is destroyed when the surface is destroyed. Because of this, the view.surface pointer is always valid and non-null. 3. The compositor's surface_list is replaced with a view_list. Due to subsurfaces, building the view list is a little more complicated than it used to be and involves building a tree of views on the fly whenever subsurfaces are used. However, this means that backends can remain completely subsurface-agnostic. 4. Surfaces and views both keep track of which outputs they are on. 5. The weston_surface structure now has width and height fields. These are populated when a new buffer is attached before surface.configure is called. This is because there are many surface-based operations that really require the width and height and digging through the views didn't work well. Signed-off-by: Jason Ekstrand <jason@jlekstrand.net>

Split the geometry information from weston_surface out into weston_view The weston_surface structure is split into two structures: * The weston_surface structure storres everything required for a client-side or server-side surface. This includes buffers; callbacks; backend private data; input, damage, and opaque regions; and a few other bookkeeping bits. * The weston_view structure represents an entity in the scenegraph and storres all of the geometry information. This includes clip region, alpha, position, and the transformation list as well as all of the temporary information derived from the geometry state. Because a view, and not a surface, is a scenegraph element, the view is what is placed in layers and planes. There are a few things worth noting about the surface/view split: 1. This is *not* a modification to the protocol. It is, instead, a modification to Weston's internal scenegraph to allow a single surface to exist in multiple places at a time. Clients are completely unaware of how many views to a particular surface exist. 2. A view is considered a direct child of a surface and is destroyed when the surface is destroyed. Because of this, the view.surface pointer is always valid and non-null. 3. The compositor's surface_list is replaced with a view_list. Due to subsurfaces, building the view list is a little more complicated than it used to be and involves building a tree of views on the fly whenever subsurfaces are used. However, this means that backends can remain completely subsurface-agnostic. 4. Surfaces and views both keep track of which outputs they are on. 5. The weston_surface structure now has width and height fields. These are populated when a new buffer is attached before surface.configure is called. This is because there are many surface-based operations that really require the width and height and digging through the views didn't work well. Signed-off-by: Jason Ekstrand <jason@jlekstrand.net>

shell: keyboard focus and restacking fixes for sub-surfaces The shell needs to redirect some actions to the parent surface, when they originally target a sub-surface. This patch implements the following: - Move, resize, and rotate bindings always target the parent surface. - Opacity (full-surface alpha) binding targets the parent surface. This is broken, because it should change the opacity of the whole compound window, which is difficult to implement in the renderer. - click_to_activate_binding() needs to check the shell surface type from the main surface, because sub-surface would produce SHELL_SURFACE_NONE and prevent activation. - Also activate() needs to check the type from the main surface, and restack the main surface. Keyboard focus is assigned to the original (sub-)surface. - focus_state_surface_destroy() needs to handle sub-surfaces: only the main surface will be in a layer list. If the destroyed surface is indeed a sub-surface, activate the main surface next. This way a client that destroys a focused sub-surface still retains focus in the same window. - The workspace_manager.move_surface request can accept also sub-surfaces, and it will move the corresponding main surface. Changes in v2: - do not special-case keyboard focus for sub-surfaces - fix surface type checks for sub-surfaces in shell, fix restacking of sub-surfaces in shell, fix focus_state_surface_destroy() Changes in v3: - Renamed weston_surface_get_parent() to weston_surface_get_main_surface() to be more explicit that this is about sub-surfaces - Fixed move_surface_to_workspace() to handle keyboard focus on a sub-surface. - Used a temporary variable in several places to clarify code, instead of reassigning a variable. - Fixed workspace_manager_move_surface() to deal with sub-surfaces.

shell: keyboard focus and restacking fixes for sub-surfaces The shell needs to redirect some actions to the parent surface, when they originally target a sub-surface. This patch implements the following: - Move, resize, and rotate bindings always target the parent surface. - Opacity (full-surface alpha) binding targets the parent surface. This is broken, because it should change the opacity of the whole compound window, which is difficult to implement in the renderer. - click_to_activate_binding() needs to check the shell surface type from the main surface, because sub-surface would produce SHELL_SURFACE_NONE and prevent activation. - Also activate() needs to check the type from the main surface, and restack the main surface. Keyboard focus is assigned to the original (sub-)surface. - focus_state_surface_destroy() needs to handle sub-surfaces: only the main surface will be in a layer list. If the destroyed surface is indeed a sub-surface, activate the main surface next. This way a client that destroys a focused sub-surface still retains focus in the same window. - The workspace_manager.move_surface request can accept also sub-surfaces, and it will move the corresponding main surface. Changes in v2: - do not special-case keyboard focus for sub-surfaces - fix surface type checks for sub-surfaces in shell, fix restacking of sub-surfaces in shell, fix focus_state_surface_destroy() Changes in v3: - Renamed weston_surface_get_parent() to weston_surface_get_main_surface() to be more explicit that this is about sub-surfaces - Fixed move_surface_to_workspace() to handle keyboard focus on a sub-surface. - Used a temporary variable in several places to clarify code, instead of reassigning a variable. - Fixed workspace_manager_move_surface() to deal with sub-surfaces.

shell: keyboard focus and restacking fixes for sub-surfaces The shell needs to redirect some actions to the parent surface, when they originally target a sub-surface. This patch implements the following: - Move, resize, and rotate bindings always target the parent surface. - Opacity (full-surface alpha) binding targets the parent surface. This is broken, because it should change the opacity of the whole compound window, which is difficult to implement in the renderer. - click_to_activate_binding() needs to check the shell surface type from the main surface, because sub-surface would produce SHELL_SURFACE_NONE and prevent activation. - Also activate() needs to check the type from the main surface, and restack the main surface. Keyboard focus is assigned to the original (sub-)surface. - focus_state_surface_destroy() needs to handle sub-surfaces: only the main surface will be in a layer list. If the destroyed surface is indeed a sub-surface, activate the main surface next. This way a client that destroys a focused sub-surface still retains focus in the same window. - The workspace_manager.move_surface request can accept also sub-surfaces, and it will move the corresponding main surface. Changes in v2: - do not special-case keyboard focus for sub-surfaces - fix surface type checks for sub-surfaces in shell, fix restacking of sub-surfaces in shell, fix focus_state_surface_destroy() Changes in v3: - Renamed weston_surface_get_parent() to weston_surface_get_main_surface() to be more explicit that this is about sub-surfaces - Fixed move_surface_to_workspace() to handle keyboard focus on a sub-surface. - Used a temporary variable in several places to clarify code, instead of reassigning a variable. - Fixed workspace_manager_move_surface() to deal with sub-surfaces.

Split the geometry information from weston_surface out into weston_view The weston_surface structure is split into two structures: * The weston_surface structure storres everything required for a client-side or server-side surface. This includes buffers; callbacks; backend private data; input, damage, and opaque regions; and a few other bookkeeping bits. * The weston_view structure represents an entity in the scenegraph and storres all of the geometry information. This includes clip region, alpha, position, and the transformation list as well as all of the temporary information derived from the geometry state. Because a view, and not a surface, is a scenegraph element, the view is what is placed in layers and planes. There are a few things worth noting about the surface/view split: 1. This is *not* a modification to the protocol. It is, instead, a modification to Weston's internal scenegraph to allow a single surface to exist in multiple places at a time. Clients are completely unaware of how many views to a particular surface exist. 2. A view is considered a direct child of a surface and is destroyed when the surface is destroyed. Because of this, the view.surface pointer is always valid and non-null. 3. The compositor's surface_list is replaced with a view_list. Due to subsurfaces, building the view list is a little more complicated than it used to be and involves building a tree of views on the fly whenever subsurfaces are used. However, this means that backends can remain completely subsurface-agnostic. 4. Surfaces and views both keep track of which outputs they are on. 5. The weston_surface structure now has width and height fields. These are populated when a new buffer is attached before surface.configure is called. This is because there are many surface-based operations that really require the width and height and digging through the views didn't work well. Signed-off-by: Jason Ekstrand <jason@jlekstrand.net>

Split the geometry information from weston_surface out into weston_view The weston_surface structure is split into two structures: * The weston_surface structure storres everything required for a client-side or server-side surface. This includes buffers; callbacks; backend private data; input, damage, and opaque regions; and a few other bookkeeping bits. * The weston_view structure represents an entity in the scenegraph and storres all of the geometry information. This includes clip region, alpha, position, and the transformation list as well as all of the temporary information derived from the geometry state. Because a view, and not a surface, is a scenegraph element, the view is what is placed in layers and planes. There are a few things worth noting about the surface/view split: 1. This is *not* a modification to the protocol. It is, instead, a modification to Weston's internal scenegraph to allow a single surface to exist in multiple places at a time. Clients are completely unaware of how many views to a particular surface exist. 2. A view is considered a direct child of a surface and is destroyed when the surface is destroyed. Because of this, the view.surface pointer is always valid and non-null. 3. The compositor's surface_list is replaced with a view_list. Due to subsurfaces, building the view list is a little more complicated than it used to be and involves building a tree of views on the fly whenever subsurfaces are used. However, this means that backends can remain completely subsurface-agnostic. 4. Surfaces and views both keep track of which outputs they are on. 5. The weston_surface structure now has width and height fields. These are populated when a new buffer is attached before surface.configure is called. This is because there are many surface-based operations that really require the width and height and digging through the views didn't work well. Signed-off-by: Jason Ekstrand <jason@jlekstrand.net>

Split the geometry information from weston_surface out into weston_view The weston_surface structure is split into two structures: * The weston_surface structure storres everything required for a client-side or server-side surface. This includes buffers; callbacks; backend private data; input, damage, and opaque regions; and a few other bookkeeping bits. * The weston_view structure represents an entity in the scenegraph and storres all of the geometry information. This includes clip region, alpha, position, and the transformation list as well as all of the temporary information derived from the geometry state. Because a view, and not a surface, is a scenegraph element, the view is what is placed in layers and planes. There are a few things worth noting about the surface/view split: 1. This is *not* a modification to the protocol. It is, instead, a modification to Weston's internal scenegraph to allow a single surface to exist in multiple places at a time. Clients are completely unaware of how many views to a particular surface exist. 2. A view is considered a direct child of a surface and is destroyed when the surface is destroyed. Because of this, the view.surface pointer is always valid and non-null. 3. The compositor's surface_list is replaced with a view_list. Due to subsurfaces, building the view list is a little more complicated than it used to be and involves building a tree of views on the fly whenever subsurfaces are used. However, this means that backends can remain completely subsurface-agnostic. 4. Surfaces and views both keep track of which outputs they are on. 5. The weston_surface structure now has width and height fields. These are populated when a new buffer is attached before surface.configure is called. This is because there are many surface-based operations that really require the width and height and digging through the views didn't work well. Signed-off-by: Jason Ekstrand <jason@jlekstrand.net>

Split the geometry information from weston_surface out into weston_view The weston_surface structure is split into two structures: * The weston_surface structure storres everything required for a client-side or server-side surface. This includes buffers; callbacks; backend private data; input, damage, and opaque regions; and a few other bookkeeping bits. * The weston_view structure represents an entity in the scenegraph and storres all of the geometry information. This includes clip region, alpha, position, and the transformation list as well as all of the temporary information derived from the geometry state. Because a view, and not a surface, is a scenegraph element, the view is what is placed in layers and planes. There are a few things worth noting about the surface/view split: 1. This is *not* a modification to the protocol. It is, instead, a modification to Weston's internal scenegraph to allow a single surface to exist in multiple places at a time. Clients are completely unaware of how many views to a particular surface exist. 2. A view is considered a direct child of a surface and is destroyed when the surface is destroyed. Because of this, the view.surface pointer is always valid and non-null. 3. The compositor's surface_list is replaced with a view_list. Due to subsurfaces, building the view list is a little more complicated than it used to be and involves building a tree of views on the fly whenever subsurfaces are used. However, this means that backends can remain completely subsurface-agnostic. 4. Surfaces and views both keep track of which outputs they are on. 5. The weston_surface structure now has width and height fields. These are populated when a new buffer is attached before surface.configure is called. This is because there are many surface-based operations that really require the width and height and digging through the views didn't work well. Signed-off-by: Jason Ekstrand <jason@jlekstrand.net>

Split the geometry information from weston_surface out into weston_view The weston_surface structure is split into two structures: * The weston_surface structure storres everything required for a client-side or server-side surface. This includes buffers; callbacks; backend private data; input, damage, and opaque regions; and a few other bookkeeping bits. * The weston_view structure represents an entity in the scenegraph and storres all of the geometry information. This includes clip region, alpha, position, and the transformation list as well as all of the temporary information derived from the geometry state. Because a view, and not a surface, is a scenegraph element, the view is what is placed in layers and planes. There are a few things worth noting about the surface/view split: 1. This is *not* a modification to the protocol. It is, instead, a modification to Weston's internal scenegraph to allow a single surface to exist in multiple places at a time. Clients are completely unaware of how many views to a particular surface exist. 2. A view is considered a direct child of a surface and is destroyed when the surface is destroyed. Because of this, the view.surface pointer is always valid and non-null. 3. The compositor's surface_list is replaced with a view_list. Due to subsurfaces, building the view list is a little more complicated than it used to be and involves building a tree of views on the fly whenever subsurfaces are used. However, this means that backends can remain completely subsurface-agnostic. 4. Surfaces and views both keep track of which outputs they are on. 5. The weston_surface structure now has width and height fields. These are populated when a new buffer is attached before surface.configure is called. This is because there are many surface-based operations that really require the width and height and digging through the views didn't work well. Signed-off-by: Jason Ekstrand <jason@jlekstrand.net>

shell: keyboard focus and restacking fixes for sub-surfaces The shell needs to redirect some actions to the parent surface, when they originally target a sub-surface. This patch implements the following: - Move, resize, and rotate bindings always target the parent surface. - Opacity (full-surface alpha) binding targets the parent surface. This is broken, because it should change the opacity of the whole compound window, which is difficult to implement in the renderer. - click_to_activate_binding() needs to check the shell surface type from the main surface, because sub-surface would produce SHELL_SURFACE_NONE and prevent activation. - Also activate() needs to check the type from the main surface, and restack the main surface. Keyboard focus is assigned to the original (sub-)surface. - focus_state_surface_destroy() needs to handle sub-surfaces: only the main surface will be in a layer list. If the destroyed surface is indeed a sub-surface, activate the main surface next. This way a client that destroys a focused sub-surface still retains focus in the same window. - The workspace_manager.move_surface request can accept also sub-surfaces, and it will move the corresponding main surface. Changes in v2: - do not special-case keyboard focus for sub-surfaces - fix surface type checks for sub-surfaces in shell, fix restacking of sub-surfaces in shell, fix focus_state_surface_destroy() Changes in v3: - Renamed weston_surface_get_parent() to weston_surface_get_main_surface() to be more explicit that this is about sub-surfaces - Fixed move_surface_to_workspace() to handle keyboard focus on a sub-surface. - Used a temporary variable in several places to clarify code, instead of reassigning a variable. - Fixed workspace_manager_move_surface() to deal with sub-surfaces.

Split the geometry information from weston_surface out into weston_view The weston_surface structure is split into two structures: * The weston_surface structure storres everything required for a client-side or server-side surface. This includes buffers; callbacks; backend private data; input, damage, and opaque regions; and a few other bookkeeping bits. * The weston_view structure represents an entity in the scenegraph and storres all of the geometry information. This includes clip region, alpha, position, and the transformation list as well as all of the temporary information derived from the geometry state. Because a view, and not a surface, is a scenegraph element, the view is what is placed in layers and planes. There are a few things worth noting about the surface/view split: 1. This is *not* a modification to the protocol. It is, instead, a modification to Weston's internal scenegraph to allow a single surface to exist in multiple places at a time. Clients are completely unaware of how many views to a particular surface exist. 2. A view is considered a direct child of a surface and is destroyed when the surface is destroyed. Because of this, the view.surface pointer is always valid and non-null. 3. The compositor's surface_list is replaced with a view_list. Due to subsurfaces, building the view list is a little more complicated than it used to be and involves building a tree of views on the fly whenever subsurfaces are used. However, this means that backends can remain completely subsurface-agnostic. 4. Surfaces and views both keep track of which outputs they are on. 5. The weston_surface structure now has width and height fields. These are populated when a new buffer is attached before surface.configure is called. This is because there are many surface-based operations that really require the width and height and digging through the views didn't work well. Signed-off-by: Jason Ekstrand <jason@jlekstrand.net>

shell: keyboard focus and restacking fixes for sub-surfaces The shell needs to redirect some actions to the parent surface, when they originally target a sub-surface. This patch implements the following: - Move, resize, and rotate bindings always target the parent surface. - Opacity (full-surface alpha) binding targets the parent surface. This is broken, because it should change the opacity of the whole compound window, which is difficult to implement in the renderer. - click_to_activate_binding() needs to check the shell surface type from the main surface, because sub-surface would produce SHELL_SURFACE_NONE and prevent activation. - Also activate() needs to check the type from the main surface, and restack the main surface. Keyboard focus is assigned to the original (sub-)surface. - focus_state_surface_destroy() needs to handle sub-surfaces: only the main surface will be in a layer list. If the destroyed surface is indeed a sub-surface, activate the main surface next. This way a client that destroys a focused sub-surface still retains focus in the same window. - The workspace_manager.move_surface request can accept also sub-surfaces, and it will move the corresponding main surface. Changes in v2: - do not special-case keyboard focus for sub-surfaces - fix surface type checks for sub-surfaces in shell, fix restacking of sub-surfaces in shell, fix focus_state_surface_destroy() Changes in v3: - Renamed weston_surface_get_parent() to weston_surface_get_main_surface() to be more explicit that this is about sub-surfaces - Fixed move_surface_to_workspace() to handle keyboard focus on a sub-surface. - Used a temporary variable in several places to clarify code, instead of reassigning a variable. - Fixed workspace_manager_move_surface() to deal with sub-surfaces.

shell: keyboard focus and restacking fixes for sub-surfaces The shell needs to redirect some actions to the parent surface, when they originally target a sub-surface. This patch implements the following: - Move, resize, and rotate bindings always target the parent surface. - Opacity (full-surface alpha) binding targets the parent surface. This is broken, because it should change the opacity of the whole compound window, which is difficult to implement in the renderer. - click_to_activate_binding() needs to check the shell surface type from the main surface, because sub-surface would produce SHELL_SURFACE_NONE and prevent activation. - Also activate() needs to check the type from the main surface, and restack the main surface. Keyboard focus is assigned to the original (sub-)surface. - focus_state_surface_destroy() needs to handle sub-surfaces: only the main surface will be in a layer list. If the destroyed surface is indeed a sub-surface, activate the main surface next. This way a client that destroys a focused sub-surface still retains focus in the same window. - The workspace_manager.move_surface request can accept also sub-surfaces, and it will move the corresponding main surface.

Split the geometry information from weston_surface out into weston_view The weston_surface structure is split into two structures: * The weston_surface structure storres everything required for a client-side or server-side surface. This includes buffers; callbacks; backend private data; input, damage, and opaque regions; and a few other bookkeeping bits. * The weston_view structure represents an entity in the scenegraph and storres all of the geometry information. This includes clip region, alpha, position, and the transformation list as well as all of the temporary information derived from the geometry state. Because a view, and not a surface, is a scenegraph element, the view is what is placed in layers and planes. There are a few things worth noting about the surface/view split: 1. This is *not* a modification to the protocol. It is, instead, a modification to Weston's internal scenegraph to allow a single surface to exist in multiple places at a time. Clients are completely unaware of how many views to a particular surface exist. 2. A view is considered a direct child of a surface and is destroyed when the surface is destroyed. Because of this, the view.surface pointer is always valid and non-null. 3. The compositor's surface_list is replaced with a view_list. Due to subsurfaces, building the view list is a little more complicated than it used to be and involves building a tree of views on the fly whenever subsurfaces are used. However, this means that backends can remain completely subsurface-agnostic. 4. Surfaces and views both keep track of which outputs they are on. 5. The weston_surface structure now has width and height fields. These are populated when a new buffer is attached before surface.configure is called. This is because there are many surface-based operations that really require the width and height and digging through the views didn't work well. Signed-off-by: Jason Ekstrand <jason@jlekstrand.net>

Because of this, the view.surface pointer is always valid and non-null. 3. The compositor's surface_list is replaced with a view_list. Due to subsurfaces, building the view list is a little more complicated than it used to be and involves building a tree of views on the fly whenever subsurfaces are used. However, this means that backends can remain completely subsurface-agnostic. 4. Surfaces and views both keep track of which outputs they are on. 5.

Split the geometry information from weston_surface out into weston_view The weston_surface structure is split into two structures: * The weston_surface structure storres everything required for a client-side or server-side surface. This includes buffers; callbacks; backend private data; input, damage, and opaque regions; and a few other bookkeeping bits. * The weston_view structure represents an entity in the scenegraph and storres all of the geometry information. This includes clip region, alpha, position, and the transformation list as well as all of the temporary information derived from the geometry state. Because a view, and not a surface, is a scenegraph element, the view is what is placed in layers and planes. There are a few things worth noting about the surface/view split: 1. This is *not* a modification to the protocol. It is, instead, a modification to Weston's internal scenegraph to allow a single surface to exist in multiple places at a time. Clients are completely unaware of how many views to a particular surface exist. 2. A view is considered a direct child of a surface and is destroyed when the surface is destroyed. Because of this, the view.surface pointer is always valid and non-null. 3. The compositor's surface_list is replaced with a view_list. Due to subsurfaces, building the view list is a little more complicated than it used to be and involves building a tree of views on the fly whenever subsurfaces are used. However, this means that backends can remain completely subsurface-agnostic. 4. Surfaces and views both keep track of which outputs they are on. 5. The weston_surface structure now has width and height fields. These are populated when a new buffer is attached before surface.configure is called. This is because there are many surface-based operations that really require the width and height and digging through the views didn't work well. Signed-off-by: Jason Ekstrand <jason@jlekstrand.net>

Split the geometry information from weston_surface out into weston_view The weston_surface structure is split into two structures: * The weston_surface structure storres everything required for a client-side or server-side surface. This includes buffers; callbacks; backend private data; input, damage, and opaque regions; and a few other bookkeeping bits. * The weston_view structure represents an entity in the scenegraph and storres all of the geometry information. This includes clip region, alpha, position, and the transformation list as well as all of the temporary information derived from the geometry state. Because a view, and not a surface, is a scenegraph element, the view is what is placed in layers and planes. There are a few things worth noting about the surface/view split: 1. This is *not* a modification to the protocol. It is, instead, a modification to Weston's internal scenegraph to allow a single surface to exist in multiple places at a time. Clients are completely unaware of how many views to a particular surface exist. 2. A view is considered a direct child of a surface and is destroyed when the surface is destroyed. Because of this, the view.surface pointer is always valid and non-null. 3. The compositor's surface_list is replaced with a view_list. Due to subsurfaces, building the view list is a little more complicated than it used to be and involves building a tree of views on the fly whenever subsurfaces are used.

Split the geometry information from weston_surface out into weston_view The weston_surface structure is split into two structures: * The weston_surface structure storres everything required for a client-side or server-side surface. This includes buffers; callbacks; backend private data; input, damage, and opaque regions; and a few other bookkeeping bits. * The weston_view structure represents an entity in the scenegraph and storres all of the geometry information. This includes clip region, alpha, position, and the transformation list as well as all of the temporary information derived from the geometry state. Because a view, and not a surface, is a scenegraph element, the view is what is placed in layers and planes. There are a few things worth noting about the surface/view split: 1. This is *not* a modification to the protocol. It is, instead, a modification to Weston's internal scenegraph to allow a single surface to exist in multiple places at a time. Clients are completely unaware of how many views to a particular surface exist. 2. A view is considered a direct child of a surface and is destroyed when the surface is destroyed. Because of this, the view.surface pointer is always valid and non-null. 3. The compositor's surface_list is replaced with a view_list. Due to subsurfaces, building the view list is a little more complicated than it used to be and involves building a tree of views on the fly whenever subsurfaces are used. However, this means that backends can remain completely subsurface-agnostic. 4. Surfaces and views both keep track of which outputs they are on. 5. The weston_surface structure now has width and height fields. These are populated when a new buffer is attached before surface.configure is called. This is because there are many surface-based operations that really require the width and height and digging through the views didn't work well. Signed-off-by: Jason Ekstrand <jason@jlekstrand.net>
