Robert Mader dfd58ca8f1 clutter/actor: Extend caching in apply_relative_transformation_matrix
Apart from a few edge cases we can avoid walking the tree and transform
to the ancestor coordinate space by multiplying the actor stage-relative
matrix with the inverse of the ancestor's stage-relative matrix.

Since the stage-relative matrices are cached, this reduces the number of
matrix multiplications we do in many situations considerably.
