We were force normalising the result of matrix * normal, which looked correct in most cases. But this didn't preserve the scaling of the matrix, or the scaling of the model normals which resulted in many over bright areas. On it's own this generally worked, but games like Star Wars looked quite broken. Harry correctly figured out if you scale these normals by the scaling value that is sometimes present in the culling nodes the lighting looks correct. Still more work to do to correctly figure out the model3's lighting model.

Implement unclamped light model based upon Harry's findings. Unknown how this is turned on/off.

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.

Replace glsl 3 function. Apparently this doesn't work on OS X.

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.

Stencil layered polys, fixes shadow z fighting in some of the games. Other games maybe using stipple alpha (yuck), not sure yet.

finish front/back face culling code based on matrix determinant. Optimised opengl to avoid redundant state changes.
