The surface type now no longer changes and we track pending state changes in
next_state. Instead of testing type != next_type to detect changes in
state, we just look at state_changed.
An xwayland surface corresponds to a override-redirect window under X,
which is typically a menu or a popup window. They typically appear
with a keyboard and mouse grab and by nature of being override-redirect
these window can appear anywhere on screen and in the stack.
We need to resort to heuristics to decide where to place the
override-redirect in our surface stack, and for now we'll just put it on
top of everything. That's going to be correct for almost all cases of
clicking to open a menu, but we can revisit and refine if we run into
a case that needs better handling.
Just as for set_maximized() we can move the setting of the fullscreen and
state_changed flags into the common set_fullscreen() function. This
function is also used from the xwayland wm to set fullscreen windows, and
with this change that now works again.
We can set the maximized and state_changed flags in set_maximized(),
which is shared between shell_surface_set_maximized() and
xdg_surface_set_maximized().
Since internally there's no more SHELL_SURFACE_FULLSCREEN and
SHELL_SURFACE_MAXIMIZED, the surface must be set to
SHELL_SURFACE_TOPLEVEL on the respective functions.
This fixes the bug when clients start already in fullscreen mode. In
that case, they aren't set first to toplevel, and then change to
fullscreen. They are set as fullscreen directly, not receiving the
SHELL_SURFACE_TOPLEVEL type on the set_fullscreen function.
The parent update on set_maximized and set_fullscreen is a behavior of
wl_shell.
That does not happen on xdg-shell, so it can't be in the set_fullscreen
and set_maximized common code, but rather in the wl_shell_surface
interfaces.
These surface types don't exist anymore inside weston desktop shell
implementation. They are just exposed as wl_shell surface types, but
internally the implementation is done with surface states.
The previous behavior (setting a surface type unsets another one) still
happens when using wl_shell. This change is mainly done as a refactory
to allow xdg-shell to use the same code.
This has a couple of additional implications for the internal weston API:
1) weston_view_configure no longer exists. Use weston_view_set_position
instead.
2) The weston_surface.configure callback no longer takes a width and
height. If you need these, surface.width/height are set before
configure is called. If you need to know when the width/height
changes, you must track that yourself.
The default can be set by passing WESTON_SHELL_CLIENT as an argument
to configure, similarly to WESTON_NATIVE_BACKEND.

Always put them as the top-most layer in the layer list of their parent.
This ensures that, for example, the popup menu produced by
right-clicking on a surface (which is not currently at the top of the
stacking order in the current workspace) is displayed at the top of the
stacking order.
This ensures transient surfaces are included in the layer of their
parent, even if the parent later changes layers. It achieves this by
recursively changing the layers of all children of a surface when that
surface’s layer is changed. The recursion is unbounded unless transient
surfaces are restricted to not being children of other popup or transient
surfaces.
This fixes a bug whereby a surface which is transient for a fullscreen
surface could end up being stacked below it.

It’s tied too deeply into the shell’s window stacking and ordering code
to legitimately be split out into compositor.c. Inline it in the shell,
and refactor some code around it a little, tidying up the stacking
behaviour for fullscreen surfaces.
This will be used more extensively in the next few commits, where shsurf
layering is handled more explicitly when changing the type of a surface.
This commit introduces the minor functional change that map() will now
always add the new surface to a layer list, as
shell_surface_calculate_layer_link() always returns a non-NULL link
element. This affects fullscreen and ‘none’ surfaces (which are now added
to the fullscreen and current workspace’s layer list, respectively).
This is in preparation for unifying how surface layering works. It
introduces the small functional change that fullscreen, maximized and
top-level surfaces now explicitly have no parent surface. Only popup and
transient surfaces have a non-NULL parent.
This fixes two GCC warnings when compiling with -Wswitch-enum
-Wswitch-default, and makes it clearer that those cases have been
thought about explicitly when writing the code, rather than just being
forgotten.

full screen black_surface doesn't have associated wl_buffer, so
black_surface->width and height can't get value through
weston_surface_commit(). then weston_surface_damage(black_surface)
will be wrong in shell_stack_fullscreen(), the result is that we
can't see a full screen view whe APP window's size isn't equal to
output's size like running weston-gears

Gather the variables affecting the coordinate transformations between
buffer and local coordinates into a new struct weston_buffer_viewport.
This will be more useful later, when the crop & scale extension is
implemented.
We no longer receive an exposay_binding() call while exposay
is in-flight as we have grabbed the keyboard, so we need to
listen on the modifiers callback for the modifier press and
release.
It's possible for a pointer's focus to be null, e.g. because
the focus surface has been bestroyed. Prevent a crash when
that happens and a client takes too long to respond to a ping.

This causes the surface to get the keyboard focus, which in turn
causes focus-animation to nicely work with exposay, making the
not focused surfaces to be dimmed.

Exposay provides window overview functions which, when a key which
produces the binding modifier is pressed on its own, scales all
currently-open windows down to be shown overlaid on the desktop,
providing keyboard and mouse navigation to be able to switch window
focus.

When enabled, this will make all but the keyboard-focused window dim.
Also the background gets dimmed, if there are any windows open. The
panel is not dimmed.
When the keyboard focus changes, the change in dimming is animated.
The dimming is implemented with transparent solid-color surfaces, two at
most. The net effect of two overlapping dim surfaces is kept constant
during animations (stable fade animation).
There is a new weston.ini option "focus-animation", that defaults to
none, and can be set to "dim-layer" to enable the focus change
animation.
[pq: Sliced, squashed, and rebased the patch series. Fixed surface alpha
interaction with the switcher. Wrote the commit message.]
