Transformation returns the transformation matrix that should be applied to the surface.

By default when there are no transformations this will be the identity matrix.

Warning: As this functionality is presently only used by mir_demo_standalone_render_surfaces for rotations it may be deprecated in future. It is expected that real transformations may become more transient things (e.g. applied by animation logic externally instead of being a semi-permanent attribute of the surface itself).
