I was wondering if anyone has done any image work with X.  In particular,
I am trying to display a raster bitmap on an IBM PS/2 with an 8514 display.

As a testing drawing I'm using a bitmap which is 1600 x 2200 bits
(8"x11" at 200 bits/inch).  My problem isn't getting it to work...using 
an XImage structure and calling XPutImage() works great.  It's just slower
than the proverbial molasses (IMHO :>).

As an example of what I'm trying to do, there is a cool client from the
R4 distribution:  xgc.  On my Suns (3/50, 3/60, 4/65) doing the XPutImage
works very well.  When I run it on the PS/2 I thought the server had
crashed it took so long!

The performance is so abysmal I can't believe there isn't a work around except
for the obvious one of not using the PS/2! :>

Any help would be greatly!!! appreciated.
