I have been using XFillRectangles to draw up to approximately 20,000
rectangles and have been getting the following X Protocol error:

X Protocol error:  BadLength poly request too large or internal Xlib length error
Major opcode of failed request: 70 (X_PolyFillRectangle)
Minor opcode of failed request: 0

I have discovered that I can still draw the rectangles if I lower the number
of rectangles I draw in one XFillRectangles call to something less than
8000 (9000 or greater lines causes the same error).

This problem has probably been hashed over before and is probably fixed
under R4, but I need to use R3.  Is just lowering the number of rectangles
to less than 8000 going to fix the problem for all time, or is it going
to seek up on me under different circumstances?  Also, do XDrawRectangles,
XDrawLines, and XDrawPoints suffer from the same malady?

Thanks for any help you can give me.
