I would like to have opinions about the idea "graphics being a file
descriptor".  The implement is irrevent for the discussion. Some
imagination is required.

Why do you insist on referring to "file descriptors"?  That's a specific
term with a specific meaning: a small integer value used in POSIX I/O
(not in standard C).

If you mean FILE* pointers, the discussion might have some relevance to
C.  If you really mean POSIX file descriptors, comp.unix.programmer
might be a better place.

Sure, you could have a graphics system where a program interacts with
the display by reading and writing to FILE* pointers.  You'd have to
encode the operations and returned data as streams of bytes.  I'm not
convinced there would be much advantage.
