Saver tries to pre-transfom to skip the matrix data, but it missed the case - transformed stroking, we skip it also only when xy scaling factors are same excluding the dash properties, because scaled of the stroking is depent on the engines, we have no idea of the proper input data in advance. @Issues: https://github.com/Samsung/thorvg/issues/773
