It seems we used to rely on the repaint scheduled by the cursor motion.
But if there's no cursor, there's no cursor motion, so we need to schedule
our own repaint.

krh: Edited to make message a litle more precise and added a check to
verify XDG_RUNTIME_DIR ownership and access mode.
Since we now batch up damage and only handle it at repaint time, we need
to apply it in case a buffer is destroyed so we don't lose it.
Ander found the problem, but we need to fix it in the compositor so we
don't change the behavior of the compositor.
weston_surface_update_transform() is typically called as part of the
repaint cycle so don't schedule a repaint here. There are still a couple
of places where we call weston_surface_update_transform() manually, but
they don't rely on the repaint being scheduled.
We need to initialize prev when we handle the initial pixel in a
rectangle, or we may detect the following pixel as identical or different
when it's not. This causes the top-left pixel in a rectangle to
occasionally be wrong leaving a trail of "dirty pixels" in the capture.
This is the point where we have just finished rendering the new scene
but before we swap it to the front buffer. At this point, the
output->previous_damage region exactly corresponds to what was just
renders, as compared to previous frame.
We start tracking which hardware plane a surface is displayed on, which
lets us avoid generating damage when a hardware overlay/cursor is moved
around.
EGLDisplay is helpfully typedeffed as void *, which means that you won't
get conflicting-pointer-type warnings if you accidentally confuse it
with weston_compositor::wl_display. Rename it to make it more clear
which display you're dealing with, and also rename compositor-wayland's
parent.display member to parent.wl_display.

If we can't find a cursor for whatever reason, don't crash the client in
pointer_surface_frame_callback.

We transform the surface damage to global damage at weston_output_repaint()
time. This way we don't touch the transform when it might not be valid
and in case of overlapping damage, we only copy pixels once for shm textures.
The launcher before in tablet-shell just draw the icon and will
not activate a client. This patch makes the launcher as sub-widget
of homescreen, and implements enter/leave/button/redraw hanler to
do the actual client launching action.
Expecting the link to be initialized breaks when compositor-drm.c
takes surfaces out of the list. We could fix that to also
wl_list_init() the link, but we're moving to making the surface list
local to weston_output_repaint(), rebuilt in and only valid during
weston_output_repaint() so just don't touch it instead.
Since the introduction of pointer.set_cursor(), it is possible for a
client to set the surface containing the pointer image and get frame
callbacks on it thus allowing a clear implementation of animated
cursors.
This also makes the busy cursor hack of using frame callbacks on the
busy surface unnecessary.
