V11 permits graphics to be done directly to Pixmaps, etc.  My question
is about how this is implemented.  It seems to me that in-memory
graphic routines do not need to make the expensive calls to the
server.  One way this could be implemented is to have a
device-dependent runtime library for in-memory graphics linked into
the client's program if the client chooses.

I believe that this effiency issue is important, especially for those
of us who want to (and can) create complex images in memory and then
simply BLT them onscreen.
