Legacy engine: fixed texture offsets (VON2 was broken by last commit). Texture coordinates are wrapped within the bank first and then the bank can be swapped. This also allows the full range of texture coordinate bits to be used as specified in the Pro-1000 SDK.

Legacy engine: expanded color index to 12 bits from 11. Does this affect any games?

Legacy engine: Added stencil buffering for layered models and shadows. Not as accurate as new engine because stencil buffering is applied per-model rather than per-polygon, so the entire model must consist of stencil-tested polygons. In practice, though, this seems to work fine.

Fixed fog in legacy 3D engine. Now computed same as new engine, with 4-bit light modifier and corrected fog mixing in shaders.

Updated legacy engine vertex shader to use specular shininess and coefficient along with old equation. Still not correct (too strong compared to the old method).

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).

Legacy engine: fixed per-vertex fixed shading to incorporate Ian's findings that the intensity value is signed and that fixed shading applies only when lighting is enabled

Legacy engine: preliminary per-vertex fixed shading. Only limited testing with LA Machineguns (appears to work), Sega Rally 2 (appears okay), and Scud Race (fixes expert course bridge but not other mis-colored polygons).

Fixed texture enable bit (fixes Star Wars light sabers and Sega Rally 2 cones) and added a hack for (and more comments about) color modulation. Scud Race, Sega Rally 2, LA Machineguns, etc. look correct now, but Fighting Vipers 2 shadows are no longer dark enough. Other bugs may exist.
