This protocols allows clients to describe the stereoscopic layout of
their surfaces, to make the compositor render all sides on 3DTVs or

It also gives a way for the compositor to describe the native stereo
layout of the current mode, so that clients can adapt their buffers to
do direct scanout.

This protocol aims at describing outputs in way which is more in line
with the concept of an output on desktop oriented systems.

Some information are more specific to the concept of an output for a
desktop oriented system and may not make sense in other applications,
such as IVI systems for example.

The goal is to gradually move the desktop specific concepts out of the
core wl_output protocol.

For now it just features the position and logical size which describe
the output position and size in the global compositor space.

Split out toplevel window like requests and events into a new interface
called xdg_toplevel, and turn xdg_surface into a generic base interface
which others extends.

xdg_popup is changed to extend the xdg_surface.

The configure event in xdg_surface was split up making
xdg_surface.configure an event only carrying the serial number, while a
new xdg_toplevel.configure event carries the other data previously sent
via xdg_surface.configure. xdg_toplevel.configure is made to extend,
via the latch-state mechanism, xdg_surface.configure and depends on
that event to synchronize state.

Other future xdg_surface based extensions are meant to also extend
xdg_surface.configure for relevant window type dependend state

Some application may wish to restrict their window in size, but

As a result, the compositor may try to maximize or fullscreen a window
while the client would not allow for the requested size.

Add new requests "set_max_size" and "set_min_size" to xdg-shell so that
the client can tell the compositor what would be its smallest/largest
acceptable size, and that the compositor can decide if maximize or
fullscreen is achievable, draw an accurate animation, etc.
