Dear Xpert,

	I will be doing a port of X that will take advantage of a graphics
accelerator device.

	1. From the code it seems that widelines need floating point up
to span generation thus ruling out using an accelerator that only uses
integer input parameters.  True/False ? (Do you know if anyone has 
cheated on this one?)

	2. Are there any public domain codes for decomposing general
polygons into triangles or quadrilaterals for accelerators that can't
do polygons with more than 4 corners?

	3. Got any general comments/advice on this approach?  (I'm not
looking to re-invent any well known wheels!)

	Thanks in advance for any help you can give.
PS
	Can you add me to your mailing list if you have regular mailings?
