Bug 885621. Fix gfxPattern::GetMatrix() with azure and add GetInverseMatrix(). r=bas

Currently SetMatrix will take the Inverse of the passed in matrix but GetMatrix
doesn't not invert it on the way out. This fixes that and adds a
GetInverseMatrix() so that we don't double invert it when we need the inverse.

Bug 885016. Avoid using uninitiated extend in gfxPattern. r=bas

This changes gfxPattern to use GraphicsExtend. All of the inputs and outputs
are GraphicsExtend so there's no point storing it in a type of ExtendMode. We
also intialize gfxPattern to EXTEND_NONE when constructing it for Azure.
