When we're repainting, there's no point in polling for input events.
We just read input events once before each repaint and send out events
as needed. The input events come with an accurate timestamp, so this
doesn't affect the timing information and client should always look at
the event timestamps if they're trying to determine pointer motion
speed or double click speed. If we go idle (stop repainting) we add the
input devices back into the primary main loop and wait for the next event.
This avoids waking up the compositor separately (one or more times per
frame) to handle input events. We also avoid updating cursor position
and other compositor state after the client has rendered its new
frame, reducing lag between what the client renders and the pointer
position.
I was integrating patches on the 'layers' branch and had a fixed version of
the fullscreen patch there. My master branch had the fullscreen patch with
the resize bug, and when I pushed I meant to push the layers branch to master.
Conflicts:

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.
We can now clip the surface bounding box against the previous frame
opaque clip, and then just union the result (visible damage) into
compositor->damage immediately.
Undo fullscreen in shell_unset_fullscreen(), do all the stacking order
in shell_stack_fullscreen(), and configure black surface, method in
shell_configure_fullscreen().

libbacklight is 300 lines of code in one .c file, and we're relying on
udev changes that aren't yet upstream. For now, let's just keep a
copy in weston and if the Xorg DDX drivers start using libbacklight and
it becomes more widely available, we'll make it an external dependency.
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:

If you don't have anything at ~/.config/weston-desktop-shell.ini and
have weston installed somewhere other than /usr, then this patch will
help.

We end up doing an attach at the non-fullscreen size before resizing to
fullscreen, causing the terminal to jump to the center for a frame before we
render the fullscreen image.
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.
