Daytona seems to use this completely undocumented feature of the real3d pro-1000, the ability to invert texture colours. This patch fixes the colours on the cars, and the signs which should flash by alternating their colours.

Support high priority polygons. They are treated as a separate overlay plane by the h/w. Fixes some missing fx in harley.

Dynamically calculate near/far frustum planes for each viewport priority layer by clipping the overlapping meshes with the 4 frustum planes. A bit brute forcy, but the results are great.

Support microtexture relative scale. The exact scaling values are not known, but a 2x difference between each level seems highly likely. We know from visual inspection from scud that the first level is exactly 4. The SDK has a function that accepts a float input for scale and does this. lod = (1/scale) + 0.5. If lod>3 lod = 3. So this is our best guess.

Fix the shading in scud. When lighting is disabled the fixed shading intensities appear to be offset values added to the colour value.

Support multiple microTextures, fixes crazy texturing in sega ski champ. I'm assuming microtextures are always located on the other memory bank to the base texture. This logic seems to work for all our games anyway.

Cull geometry based on the culling distances in the nodes. Should give some sort of speedup on lower end pcs where the CPU is predominantly the bottle neck.

Y texture offsets are just 5 bits. Texture coordinate wrap around happens in the same texture sheet, not into the next one. Fixes various texturing bugs in sega rally.
