Bug 1265824 - Pass the texture direct mapping info to all texture creating functions r=mattwoodrow The client side can't get the GL context in CompositorOGL. So, it can't know the texture direct mapping capability directly. This patch adds the texture direct mapping info in TextureFactoryIdentifier. Then, the client side could get the info form the TextureFactoryIdentifier. MozReview-Commit-ID: KEazDVg0p9Y
