This adds new driver hooks to allocate scanout pixmaps and changes the mode setting APIs to pass the new scanout pixmaps along from DIX. DIX is responsible for reference counting the pixmaps by tracking them through RRCrtcNotify. Signed-off-by: Keith Packard <keithp@keithp.com> Reviewed-by: Aaron Plattner <aplattner@nvidia.com>
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.
