	Hopefully this will be a simple question for someone out there who
wouldn't mind taking a second to help out a new Sun user.

	I'm learning how to draw on my Sun IPC, and in fact I've had good
luck at drawing my Mandelbrot sets using the <cgidefs.h> package, except that
calculating 30,000 x 30,000 pixels takes many many hours.  I recently ran into
the suntool graphics package and have been able to draw, but only in B/W.
I'm having trouble learning how to manipulate the PIX_SRC bit map field to 
change colors. (Or at least this is how I believe I should do it.) Is the
problem that I have to set up a color table first?  How would I go about doing 
that?  Below you will find a simple program I wrote to draw some lines, could 
someone modify it to make the lines colored. (I always learn best from 
examples.)  Thanks a million.
				Steve.
