Normalize when we render the ground.  This shouldn't be necessary, but it
looks like various parts of the code rely on RESCALE_NORMAL, which is set but
not unset in avatar/Head/Hand.  We'll have to look at that more closely later
on.
Merge pull request #784 from ey6es/master

Fix for ground rendering (on OS X): enable GL_NORMALIZE, which overrides RESCALE_NORMALS.
