d27174028e 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.

6e58bce8e5 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).

421ee253e6 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.

ffa9cae11c New tree rendering algorithm
Draw trees in two passes, opaque and transparent. This allows us to
have some transparency, which is better looking, and dispense with
sorting.
