Follow-up Comment #26, bug #45494 (project octave):

>> It makes more sense to put such effort into gl2ps to patch things back

I also though about that but think about 3D crossing patches:

clf ();
patch ([0 1 1], [0 1 0], [0 1 1], "r");
patch ([1 0 1], [0 1 0], [0 1 1], "b");
view (3);
print /tmp/foo.svg
open /tmp/foo.svg

I also though about that but one of the points of splitting polygons into
triangles is to handle color gradients. In this case it is unlikely that 2
neighbor triangles have the same color and there is nothing to pack back. 

PS: The relevant bug report for Inkscape is [1]. I know it looks like
off-topic but the discussion there is quite instructive.
