Description Roland Scheidegger 2006-05-31 16:01:45 UTC 
the SWZ opcode is not handled correctly in mesa's tnl module (in
t_vb_arbprogram.c). The results are more or less obvious wrong (for instance use
the swz2.txt test case but use only x/y/z/w and not 0/1), but I can't quite see
how it's supposed to work. It seems strange that in fact somtimes 3 RSW
instructions are generated for a single SWZ, I'd think 2 should be sufficient.
Anyway, it just plain doesn't work.

Mass version move, cvs -> git
