The copy optimization in d37329cba42fa8e72fe4be8a7be18e512268b5bd replicated a bug from last time we did a copy optimization: CopyArea is only defined for matching depths. This is only a problem at 15 vs 16 depth right now (24 vs 32 would also have matching Render formats, but they should work) but be strict in case we store other depths differently in the future. Fixes rendercheck -t blend -o src -f x4r4g4b4,x3r4g4b4 v2: Drop excessive src->depth == dst->depth check that snuck in. v3: Switch back to src->depth == dst->depth v4: Touch up commit message (s/bpp/depth).

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
