Fixes #554

Fixes #561

Note: Causes backward compat. issues for lit objects using shader library in materials bindings.

To fix: Change your material bindings
from:
u_inverseTransposeWorldViewMatrix = INVERSE_TRANSPOSE_WORLD_VIEW_MATRIX
to:
u_inverseTransposeWorldMatrix = INVERSE_TRANSPOSE_WORLD_MATRIX
