xdg-shell: Document the set_maximized and unsetmaximized requests

Browse Source 
This patch changes the semantics (compared to the previous version of
this patch) of maximizing/unmaximizing an already maximized/unmaximized
surface to always result in a configure event. Doing it this way would
be more consistent with how the compositor works regarding other
configure events i.e. send many, letting the client ignore when needed
(for example during resize).

<description summary="maximize the window">
Maximize the surface.
After requesting that the surface should be maximized, the compositor
will respond by emitting a configure event with the "maximized" state
and the required window geometry. The client should then update its
content, drawing it in a maximized state, i.e. without shadow or other
decoration outside of the window geometry. The client must also
acknowledge the configure when committing the new content (see
ack_configure).
It is up to the compositor to decide how and where to maximize the
surface, for example which output and what region of the screen should
be used.
If the surface was already maximized, the compositor will still emit
a configure event with the "maximized" state.

<description summary="unmaximize the window">
Unmaximize the surface.
After requesting that the surface should be unmaximized, the compositor
will respond by emitting a configure event without the "maximized"
state. If available, the compositor will include the window geometry
dimensions the window had prior to being maximized in the configure
request. The client must then update its content, drawing it in a
regular state, i.e. potentially with shadow, etc. The client must also
acknowledge the configure when committing the new content (see
ack_configure).
It is up to the compositor to position the surface after it was
unmaximized; usually the position the surface had before maximizing, if
applicable.
If the surface was already not maximized, the compositor will still
emit a configure event without the "maximized" state.
