I've got the GhostScript 1.2 source and have been working on the
port.  Some issues come to mind, though:

- Any ideas on how to specify (to the device)
  - Horizontal and Vertical resolution?
  - Horizontal and Vertical size?

Should I use the virtual page library by CLtd for the image (which
will allow color and fragmented bitmaps)?  Interactive drawing to a
window might be nice, too.  Should I provide the graphics primitives
(including path generation and the like) as a library callable by
other routines?

This program will require memory, but I'm trying to keep it as small
as possible.  GhostScript itself does some very nasty stuff
internally (grabbing the return address from a jump_buf structure,
doing very strange things with the stack frame inside of a
procedure, etc.) but I'll give it my best shot.  Please, any
suggestions at all are appreciated.
