The >1.10 one broke graphics. 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.
