 * 
 *  The "textureEnvs" ArrayList defines what texture environment commands 
 *  will be sent to OpenGL for the texture. Typically, this needs to hold
 *  just one TextureEnvVo, but can hold an arbitrary number, for more
 *  complex 'layering' operations.

 *  TODO: Ability to assign arbitrary UV lists per-TextureVo? (Non-trivial...)
