fix size of transparency group surface

cairo_surface_create_similar_clip calculates an incorrect surface size under rotation.  The right calculation is a bit more involved.  See _cairo_matrix_transform_bounding_box in cairo's cairo-matrix.c (http://cgit.freedesktop.org/cairo/tree/src/cairo-matrix.c#n426).  It requires transforming the four corners of the clip extents and taking the min/max of the results.  Instead, this patch lets cairo handle creating a surface of the right size.

Not only fixes the issue but cleans up the code, thanks! I've just pushed it to git master.
