Trisurf() improvements. * __go_draw_axes__.m: Revert changeset 595ee644fa6f. Properly identify RGB cdata [1x3] for patches. * trisurf.m: Correct bugs in converting between facevertexcdata and cdata. This allows caxis auto to function correctly, and properly fixes bug 35144. Add demos to explicitly test facecolor = "flat" and "interp".
