st/mesa: set MaxUnrollIterations = 255
The default was 32 for the EmitNoLoops=0 case. This allows the oZone3D soft shadows test to work properly with the vmware driver. Jose reported that SM3 supports up to 255 loop iterations. NOTE: This is a candidate for the 8.0 branch. Reviewed-by: José Fonseca <[email protected]>
