Here's a neat one: when I compiled hiview, the updated go32 and tr8900.grn
drivers worked perfectly, but when I tried to build xli (a much more useful
program) the tr8900 driver refused to render anything, yet I could get
great output using the trid89n.grd driver (although linked to the libgrx.a)

Since this older driver also works with hiview (and every sample program
I've tried) it's a good patch, but when I ran the bcc2grx test program,
I notice the polygon fill function in the old drivers is far too slow
for my purposes ... and also, the new driver gives me an extra demo in
the bccgrx test to cycle the palette on a colour wheel display.

Incidentally, I have just finished a port of the DKBTrace raytracing
package for djgpp/libgrx --- now at long last I can compile _all_ the
examples in the DKB kit.  If anyone is interested in a copy of my
changes to the DKB sources, please let me know.  Of even more esoteric
interest, I also have a (barely) functional port of the latest StarChart
'observe' and 'starXaw' programs --- I'd like to also port the XEphem
astronomical ephemeris, but for the moment the Motif-dependence is out
of my budget.
