Rather than perform an intermediate copy and expand the strip and the fan into a triangle list (thereby tripling the number of edges that the driver needs to process), allow the backend to hook directly into the appropriate Composite function. In order to extend the PictureScreen, without needlessly bumping the ABI, we move the existing copy implementations to mipict.c and assign those by default. To notify the ddx that the new entry points are available, we introduce PICTURE_SCREEN_VERSION.

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.
