Summary: non-planar patches are not supported in Octave

Details:
In Matlab, the following example gives a patch with a bent surface (similar to
two triangles sharing one edge):
vertices = [0, 1, 0; 1, 1, 0; 0, 0, 0; 0, 0, 1];
faces = [1 2 3 4];
hp = patch ('Vertices', vertices, 'Faces', faces);
While the same code sample does not error for "fltk" or "qt" in Octave, the
resulting patch is incorrect. The first edge (at [0, 1, 0]) seems to be
ignored.
For "gnuplot", this error is thrown:
error: __go_draw_axes__: gnuplot (as of v4.2) only supports 3-D filled
triangular patches
error: called from
__go_draw_axes__ at line 671 column 18
__go_draw_figure__ at line 172 column 17
__gnuplot_drawnow__ at line 86 column 5
