Flyinghead c57b2e1aa7 oit: incorrect color used when src=OTHER_COLOR if dest is 2nd accum
Using src=OTHER_COLOR with destination secondary accumulator should use
the secondary accumulator color, not the final one.
Fixes dark gun in Doom 64 with Ultra graphics (bump mapping).

Flyinghead 2653c5ed73 naomi2: fix modifier volumes clipping
Don't clip modifier volumes but tesselate triangles intersecting the
near plane. Then project clipped vertices onto it in the vertex shader.

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.

Flyinghead 79bbd86c2f rend: Fix PT polygons alpha test
Alpha test for PT polys is done after mixing texture and vertex colors
and clamping. Revert db0534d5dd. See

Fixes visible triangle arrows after selecting a character in Langrisser
Millenium.

Flyinghead 9f2ffd102c oit: Can't discard pixel in pixel shader when using 2ndary accumulator
When using the secondary accumulator as source or destination, pixel
must not be discarded even if blending results in a nop. Doing so
cancels the transfer to/from the accumulator.
