These offer a simpler and more efficient means for temporarily
transitioning to CPU-accessible memory for fallback implementations.
v2: Do not attempt fallbacks with GLAMOR_DRM_ONLY pixmaps
glamor cannot transfer pixels for GLAMOR_DRM_ONLY pixmaps using
glReadPixels and glTexSubImage2D, and so there's no way to perform
fallback operations with these pixmaps.
v3: Clear ->pbo field when deleting the PBO. Otherwise, we'd reuse
the old name next time we fall back on the pixmap, which would
potentially conflict with some other pixmap that genned a new
name, or just do a lazy allocation of the name (compat GL context,
like we currently use) or error out (core GL context, like we hope
to use some day). Also, style fixes. Changes by anholt, acked by

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.
For a comprehensive overview of X Server and X Window System, consult the
following article:
