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.

1531446fb2 From Lauri Peltonen (Zan): 
These two patches allow use of external shaders as the tree and 3d cloud
shaders. The shaders are Shaders/3dcloud.{frag|vert} and
Shaders/tree.{frag|vert}. If the shader files are not found, the
original shaders included in the source are used.

This makes testing modifications to the shaders easier and faster. End
users should see no difference when using this.
