shader optimizations
...
Use two-pass rendering for some shaders to reduce the cost of expensive shaders.
Implement some material animations using a shader uniform.
Eliminate use of gl_FrontFacing. It's too buggy on ATI/ Macintosh.

Rewrote landmass geometry shader
...
I did several optimizations, including reducing to a bare minimum
shader computations and producing the geometry as one tristrip with
degenerate triangles. The result was an increase from 14 fps to 51 fps
(NVidia 8600M, ufo, ksfo).

fix shader bugs on ATI hardware
...
The main problem was using gl_FrontMaterial.ambient with a color mode
of AMBIENT_AND_DIFFUSE i.e., the fixed function path would take both the
ambient colors from the vertex color value. Also, some vertex shaders
were not writing gl_FrontColor even though the fragment shader was
accessing gl_Color.
