Comme= nt # 12 on bug 11078= 3 from Gert Wollny 
I might add that the DIV is lowered in glsl to RCP+MUL before =
it is translated
to TGSI, so no need for it there.=20

When I look at the bicubic shader with the offending opcodes, I have to say
that using DIV there is a bit lazy, because the DIVs act on constants or
uniforms or combinations of these, and it would probably be better to pass =
them
reciprocal value in (I just don't know (yet) where the constants are actual=
ly
passed in to change this).

Anyway, since there is already a CAP for TEX_LZ I was able to create a simp=
le
fix:=20
