Remove mbe_matrix_t type. The struct mbe_matrix_t is defined in a layout accoriding definition of Cairo. It is not feasible for all graphic engine. Now, we start supporting of other graphic engine; Skia, so use type of (co_aix[6]) defined and used by MadButterfly intead of mbe_matrix_t. And, bridges of graphic engines are responsible for translate matrics into the matrix type of the graphic enigne.
