The translator map seems to work with paletted colour values too, and the result is not clamped. Colours are passed to the GPU as unsigned bytes to multiplying by 16 will overflow, so we do the logic in the shader. If we passed floats we could skip the shader logic.

Fix the sky in harley in first person mode where pixels in the sky are culled when they shouldn't be with the quad renderer. Basically we were running out of precision in a rare corner case. Doing the maths with double precision and casting back to float was enough to fix the issue.

To calculate the mipmap value the opengl needs to calculate the difference in the texture coordinates between adjacent pixels. If there are no adjacent pixels the hw may need to spawn invisible fragments outside of the visible polygon. Our algorithm was culling these out so the mipamp calculation failed for edge pixels. Anyway this fixes quad rendering looking broken with the latest nvidia drivers.

Technically backface culling should cull polys when the dot product = 0, since when it equals 0 the polys is perpendicular to the camera and thus invisible. When you complete sega rally2 (if you can get that far lol) the champagne is invisible. The reason is because all the face normals are 0. So when multiplied by the model matrix they are still 0 and get culled. Tweaking the condition to only cull polys when greater than 0 fixes this, and allows these 'bad' polys to render as they do on the model3.

Quad rendering engine. Set QuadRendering = 1 in the ini file to use, or -quad-rendering at the end of the command line to use.
