"Geometry.cpp
Make sure number of normals match number of vertices when lit or
vertex-normal pairs are separated when geometries are merged by the
optimizer.

Ancillary.cpp
Improved support for multitexture effect field and use texture
environment from .attr file.

PaletteRecords.cpp
Use search path when looking for shader files.

PrimaryRecords.cpp
Added preset uniforms "TextureUnit0", "TextureUnit1", "TextureUnit2"
and "TextureUnit3" for GLSL shaders."
