render: export TriStrip and TriFan to the drivers

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.
