This lets us mark a rectangle in a texture and force the alpha to one
inside. This is useful for textures coming from X windows, where the X
window part is xRGB, that is 32 bit RGB with an undefined alpha channel
and the decorations are rendered with a well-defined alpha channel.
wl_input_device has been both renamed and split. wl_seat is now a
virtual object representing a group of logically related input devices
with related focus.
It now only generates one event: to let clients know that it has new
capabilities. It takes requests which hand back objects for the
wl_pointer, wl_keyboard and wl_touch interfaces it exposes which all
provide the old input interface, just under different names.
This commit tracks these changes in weston and the clients, as well as
similar renames (e.g. weston_input_device -> weston_seat). Some other
changes were necessary, e.g. renaming the name for the visible mouse
sprite from 'pointer' to 'cursor' so as to not conflict.
For simplicity, every seat is always exposed with all three interfaces,
although this will change as time goes on.

Using the surface enter/leave events track which outputs the window is on and
store those in a "window_output_list" on the window.
To create this list we define a struct window_output that is the list
relationship between the window and the output.
The type of fields x and y in wl_input_device was changed to wl_fixed_t
but input_device_attach() was still using it as if it were integer.
This bug caused the pointer sprite to be configured in the wrong place
on the screen (usually outside the visible area) but it would soon be
corrected in notify_motion() making it hard to notice and usually only
causing a quick flicker.
If a client changes it's width/height values in it's widget resize handler,
the input region will be wrong because of the assumptions toytoolkit makes
in frame_resize_handler(). So far, gears is the only client that does this.
We were testing if the pointer were outside any output and doing a lot of
work to compute the bounding box of all output and then clip against that.
Just clip against previous (valid) output and don't bother with the
bounding box.
