Flyinghead d618abc320 rend: modifier volumes must be clipped
Modifier volumes should also be clipped when needed.
Implement outside clipping for non-OIT renderers.
OIT renderers are less affected since the shadowed polys themselves are
usually also clipped after shadow is applied.
Fixes overflowing shadows in baserunner cams in WSB 2K1.

Flyinghead 5eddc26850 dx11: work around some float literal precision issue with the compiler
For some reason the directx compiler doesn't convert float literal in a
deterministic way (!). A difference of one ulp can be seen between
different compilation of the same code.
This causes an issue with the rounding of the alpha value for PT polys.
