This results in invalid rendering when running a debug version of the
application.
Fix the issue by limiting the maximum values of px and py to 1.5 less
than width and height. This prevents reading past the end of the source
buffer.

Committing to an xdg_surface with a NULL buffer is currently illegal in
the mutter implementation, so this simply causes the client to error and
exit.
It seems the reason the client did this was so it could add its own
frame callback, but toytoolkit actually provides accurate everything we
need. Just use its functions instead to get the time and schedule a
redraw.

This started as a copy of simple-shm.c before it was converted to
xdg_shell.
This demo excercises the presentation feedback interface in five
different modes:
- A continuous repaint loop triggered by frame callbacks, and using
immediate commits, just gathering presentation feedback and computing
some time intervals for statistics.
- The same as above, except with 1s sleep before actually repainting as
a response to frame callback. This tests how well the compositor can
do a repaint from idle state (not continuously repainting), assuming
nothing else is causing repaints.
- A continuous repaint loop triggered by 'presented' events rather than
by frame callbacks. If Weston uses an appropriate scheduling
algorithm, this mode achieves the smallest possible frame latency
(below one output refresh period).
In all modes, all frames are pre-rendered at startup, so no rendering
happens during the animation.

When a toytoolkit client redraws, the toolkit syncs the parent and
geometry. If a client redraws often (such as the terminal drawing a huge
amount of output), this can spam the compositor with requests and may
result in the client's eventual being killed.
We don't need to send requests for changing the geometry or parent if
these haven't changed. So remember the last geometry and parent, and
update them only if needed.

If a cursor was set with wl_pointer.set_cursor but not in combination
with an action that has the side effect of damaging the region where the
cursor is positioned, it would not be drawn. This patch explicitly
schedules a repaint of the pointer sprite when it is set.
clickdot is updated to illustrate the bug; when moving the pointer over
clickdot, the pointer is hidden. When not having moved the pointer for
500 ms it is made visible using wl_pointer.set_pointer.

The experimental versioning has not been updated when it was supposed
to. Let's try to be better at it now, as xdg-shell is close to have its
first stable version.
Bump the version now to bring the world into the same exact version.
There may be some protocol changes still coming, but we try to land them
before 1.6 gets out. Those changes will bump the experimental version
again as needed.
When 1.6.0 is released, the experimental version will no longer be
bumped, and no incompatible protocol changes will be made. Xdg-shell.xml
file will move to Wayland in 1.7.0, drop the experimental versioning,
and become stable.

At the calculation of the first FPS, gears has initialized last
FPS time with gettimeofday().
But the callback_data passed in the callback of wl_surface_frame()
is the current time, in milliseconds, with an undefined base.
Because of this subtracting last FPS time from callback_data makes no sense.
For example, below is the result of running weston-gears on weston with
drm backend:
$ weston-gears
Warning: FPS count is limited by the wayland compositor or monitor refresh rate
1 frames in 1094460.125 seconds = 0.000 FPS
301 frames in 5.016 seconds = 60.008 FPS
301 frames in 5.016 seconds = 60.008 FPS
301 frames in 5.016 seconds = 60.008 FPS
As you can see, the the first FPS value is something odd.
This patch fixes it by initializing last FPS time with the callback_data passed in
the first callback.

Currently, there is a fun flicker when toggling maximization or
fullscreen on a window in mutter or more sophisicated compositors
and WMs.
What happens is that the client want so go maximized, so we
calculate the size that we want the window to resize to (640x480),
and then add on its margins to find the buffer size (+10 = 660x500),
and then send out a configure event for that size. The client
renders to that size, realizes that it's maximized, and then
says "oh hey, my margins are actually 0 now!", and so the compositor
has to send out another configure event.
In order to fix this, make the the configure request correspond to
the window geometry we'd like the window to be at. At the same time,
replace set_margin with set_window_geometry, where we specify a rect
rather than a border around the window.
In many clients of weston, Display was not being destroyed so added it.
Also destroy windows, widgets which were not being destroyed.

This allows for easily testing a compositor's damage tracking in all
currently available configurations including wl_surface.buffer_transform,
wl_surface.buffer_scale, and wl_viewport. It also includes a
--rotating-damage that flag instructs the client to change the
wl_surface.buffer_transform on every commit. This tests the compositor for
proper handling of texture uploads even when the transform has changed but
the buffer size hasn't.
Once we've updated the window state and scheduled a resize, we know that
the next frame we send to the compositor will match the configured state.
This means we can just ack the configure immediately and not jump
through hoops to try to do it from the redraw stage.
As the protocol says, the states determine how the width and height
arguments should be interpreted, so it makes logical sense to do the
interpretation after.
