You might want to look at /dev/draw of plan9. And rio, as
someone else also suggested.  /sys/src/9/port/devdraw.c on
plan9 is only about 2200 lines. You may also wish to read Rob
Pike's paper on 8 1/2 and man pages for draw(2), draw(3),
graphics(2) and rio(1) @ cat-v.org. See rio presentation @
http://herpolhode.com/rob/lec5.pdf as it lays out window
system design issues very nicely.
