Minor QuadBatch optimizations for faster 'simple state' rendering.
Added ability to skip vertex data initialization in the Quad() constructor, and then set it via a support function called setVertexData().
NOTE: Had to force-set all super() calls to the Quad() as there seems to be a bug in LoomSDK with super() default params coming through as 'null'!!!
Set the QBs native texture when adding a new Quad
Added a few questions for Ben to review, and fixed issue with static IDENTITY Matrix where the default constructor params were not being used; needed to manual specify them
