weston-launch starts weston and provides mechanism
for weston to set/drop drm master, open a tty,
and read input devices without being root.
Execution is allowed for local-active sessions
or users in the group weston-launch.
Use shell_stack_fullscreen() to raise fullscreen surface in activate(),
and before activate() a regular surface, move all the fullscreen
surfaces from fullscreen_layer to toplevel_layer.
Also add a void *private into struct wesont_surface since we already
have a configure() vfunc. That helps to get the associated fullscreen
surface of black surface.
This allows us to move the logic that calls shell->map() or
shell->configure() into shell while allowing it to be overriden for
surfaces that should not be handle by the shell, such as drag icons.
This patch adds a pointer function called configure to weston_surface,
moves the currsent surface_configure() code into shell and implements
a separate configure() for drag surfaces.
There was a lot of code here to do a lot of work we didn't need to do.
If we damage a surface with a shm buffer attached, all we need to do
is to re-upload the damaged region to the texture. As for drm buffers,
we don't assume anything changes on attach and only update the
regions the client tells us to update in the damage request.
Commit f992b2fc removed the saved keyboard focus logic to fix a crash
when the saved surface is destroyed. However, setting keyboard focus to
the first surface on the list ends up trying to set the focus to the
cursor surface most of the time. The end result is a NULL keyboard
focus.
This patch restores the saved keyboard focus logic and fixes the crash
mentioned above using a destroy listener.
Function weston_load_image() was deleted in f02a649a but the wayland
backend was not adapted to the new interface. This probably went
unoticed because the prototype for the missing function was not deleted
from compositor.h so the backend would compile without warnings.
On one hand, getopt (in particular the -o suboption syntax) sucks on the
server side, and on the client side we would like to avoid the glib
dependency. We can roll out own option parser and solve both problems
and save a few lines of code total.
This can happen for instance if the client that started the drag
crashes. Weston would crash because of the invalid surface pointed by
device->drag_surface.
Fix this by reseting the drag surface to nil on a destroy listener.
The surface data structure is now a list of list of surfaces. The core
compositor defines the fade and cursor layer, and it's up to the shell to
provide more layers for the various surface types it implements.
DPMS kicks in only when wscreensaver is launched, in the moment that shell
call lock() for the second time. Backlight control internals are managed by
libbacklight:

This allows each output back end to optimize drawing using overlay planes
and cursors (yet to be integrated). If a surface is assigned to a
plane, the back end should clear its damage field so that the later
repaint code won't look at it.
Ideally, we would want to use <modifier>+Scroll binding but that will have
to wait for axis events. For now we just use keybindings. Zoom in/out with
Super+Up/Down.
Needed for implementing drag'n'drop icons. When a drag starts, the
compositor will position the top-left corner of the client supplied
icon surface at the cursor hotspot. On the first attach to that
surface, the client may want to reposition it but shell->map did not
take sx and sy parameters.
This changes shell->map interface to take sx and sy parameters and
change dekstop shell implementation to update the position of a
surface of type none according to those parameters. Since a surface
of type none won't actually be mapped, the effect of this change is
only visible for surfaces that are made visible by the compositor.

Surfaces like drag'n'drop icons shouldn't receive events as a normal
surface but are still created by the client so add a way for the
compositor to enable or disable the picking of a client surface.

I know it's hard to figure out what the shells or backends will be
using as internal API at this point but we can try to minimize the
amount of WL_EXPORT being used anyway.

Move the surface opaque region setup from weston_surface_configure() to
weston_surface_update_transform(), so we have less reason to call
update_transform from configure. Opaque region depends on geometry,
after all.
Also move the opaque field from weston_surface to
weston_surface::transform to make this obvious.

When a transformed (rotated) surface is continuously resized from its
top-left corner, its location will drift. This is due to accumulating
rounding errors in transforming an offset from surface-local to global
coordinates in surface_attach().
Diminish the drift down to unobservable level by changing the
weston_surface global position from integer to float.
The offset transformation is now done without rounding. To preserve the
precision, wl_shell::configure() interface must use floats, and so does
weston_surface_configure(), too.
The con of this patch is that it adds inconsistency to the surface
position coordinates: sometimes they are floats, sometimes integers.
The uniform location variables should be signed, according to the OpenGL
ES 2 specification. Moreover, GL_NONE, i.e. 0, is not an invalid nor
special location; it is actually used as a valid uniform location.
Change struct weston_shader uniform members to signed.
Stop using 0 for identifying a non-existing uniform, use -1 instead.
Furthermore, as the spec says a) glGetUniformLocation() will return -1
for non-active/existing uniforms, and b) glUniform*() function will
simply ignore all calls with location -1, we can simplify the code. We
don't have to avoid locating uniforms that don't exist, and we don't
need to test for them in weston_surface_draw() either.
Remove the micro-optimisation that avoids setting 'alpha' uniform if it
has not changed, in the name of simplification.
Unify shader creation by dropping init_solid_shader(), and calling
weston_shader_init() instead. The downside is that we compile the vertex
shader twice at startup now.

weston_surface::transform.boundingbox depends on width and height, and
therefore geometry.dirty flag, so move width and height into geometry.
Fix all users and check that the dirty flag is set.

Compute a surface bounding box, especially for transformed surfaces, for
which one cannot simply use x,y,width,height.
The bounding box depends on width and height, so these are now under the
geometry.dirty flag.

Put the surface translation (absolute position) into the surface
transformations list. This allows to set additional transformations
before and after the global translation.
Having the translation cached, changing the surface x,y now requires to
set the geometry.dirty flag.

Previously, if a surface was transformed, it repainted as a whole,
regardless of the computed repaint region. As damage regions determine
repaint regions and whether a surface is considered for drawing at all,
this lead to disappearing surfaces if all surfaces were considered
transformed. Also transparent transformed surfaces were redrawn without
the surfaces below being properly redrawn, leading to alpha-saturation.
Fix that by making texture_region() use the proper global-to-surface
coordinate transformation for texture coordinates. This makes it
possible to call texture_region() also for transformed surfaces.
As texture coordinates may now lie outside the valid texture image, the
fragment shader is modified to check the fragment texture coordinates.
The special path texture_transformed_surface() is no longer used and is
removed.
This change fixes many of the rendering artifacts related to transformed
surfaces.
