Regression in 'Environment Bump Mapping' test (3DMark2001SE) with wine-1.1.10

[Milan Kostić]

Console says:

 fixme:d3d_shader:register_for_arg Unknown source argument 255

 And picture is odd with 1.1.10, in 1.1.9<= it was good i think. I
don't know exactly, but this regression can be due changes in
ati_fragment_shader.c.
