    [cairo-gstate] Fix order of matrices in _cairo_gstate_backend_to_user_rectangle()
    
    The cairo_matrix_multiply(out,a,b) docs say that it is equivalent to applying
    matrix a first, followed by b.  Looking at _cairo_gstate_backend_to_user() we should
    apply device_transform_inverse followed by ctm_inverse.  That's what we do now.
