There were a number of issues with the current implementation. It couldn't deal
with NULL mSharedHandles. Additionally it was binding things to the wrong
samplers. Finally it was not properly setting the texture transform (which
defaults to all 0). Finally in a debug build an assert would be hit upon client
shutdown due to it not clearing mDescriptor.
This patch fixes all of those issues which makes flash work again.
