Legacy renderer changes:
...
- Updated shading model. Unfortunately, it is far from perfect but it seems to be the best I can do for now. Not really much of a difference from before except that the Scud Race castle is fixed at the expense of the Yosemite level in LA Machineguns being too bright.
- Added lots of notes in the shading code.
- Passing both specular coefficient and shininess to shader. This will probably break specular lighting for now until the shader is updated to use the shininess correctly.
- Color table address in polygon RAM is now obtained from culling nodes as they are traversed (found this in the Pro-1000 SDK).

Disable light modifier on fog, seems not to work .. values don't make sense. Maybe the model3 doesn't use these.

Reverted stencil mask change. This reintroduces the Scud Race 'ROLLING START' bug. Previous 'fix' did not work for Magical Truck Adventure anyway and also broke some games (Daytona 2 transmission and course select screen, ECA title screen). The stencil mask is not shifted by 16 pixels and I suspect that either there is some unknown trick to horizontal scrolling or that the behavior is affected by hidden raster timing registers hidden in the JTAG interface.

Rewrote 2D renderer and fixed 2D layer priorities, stencil mask clipping (Scud Race 'ROLLING START'), and cleaned up code. Unfortunately, the new code is about 50% slower, mostly due to the need to perform stencil clipping after scrolling.
