It's been a while since I had to do any Xlib programming (thankfully),
but BadMatch ususally indicates that your drawable has the wrong depth.
I can't remember if you specify the depth in the Graphics Context or
when you create the drawable.
As for good Xlib references, the only one I can recommend is Volume One
of the O'Reilly X series. It's heavygoing if you read it from cover to
cover, but I found it quite rewarding. A bit like learning assembler
after you've learnt C ...
