(I actually posted this message a week or so ago, but I haven't seen a
reply and I've noticed that the header was malformed for some reason -
it both sent and copied the message to Mesa-Dev. So I'm resending it in
case it didn't actually get sent out by the list. In any case, help
would be appreciated.)

Actually, I think I may have found the tables now, assuming they're the
FX_PixelToR (G, B) ones near the top of src \ fx \ fxdd.c. However,
what I haven't been able to find is where they appear in the write paths
(my problems are with writing out coloured lines and coloured debug text
using glBitmap rather than with reading). I can see where they're used
in fxDDReadRGBASpan and fxDDReadRGBAPixels, but I can't find any
equivalent calls in e.g fxDDWriteRGBAPixels.
Frankly, I think I just don't understand this part of the pipeline at
all, but I would be grateful for any help anyone can give me here.
Many thanks,
