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.

light two-sided polygons
...
Also, remove model-default.frag; for the moment one fragment shader works for
both terrain and models.

clamp lighting values and support transparency material animation
...
The transparency animation support is a hack, but should get the job done
for a bit.

in shaders, get alpha directly from diffuse material value
...
Just like the fixed function pipeline

Created different default shaders for models.
...
These use the vertex color as the diffuse part of the lighting equation,
instead of both ambient and diffuse.
