Follow-up Comment #8, bug #32821 (project octave):

I've put together an example that indicates gnuplot can do the job, but that
there is something wrong (in __go_draw_axes__, I assume).

x = rand (100, 1);
y = rand (100, 1);
z = x.^2 + y.^2; 
tri = delaunay (x, y);
cmap = colormap (jet (64));
c1 = interp1 ([min(z), max(z)], [1, 64], z);
c2 = interp1 (cmap, c1, 'nearest');
graphics_toolkit gnuplot
close all
figure (1)
h = trisurf (tri, x, y, z, c2, "facecolor", "interp", "edgecolor", "k");
graphics_toolkit fltk
figure (2)
h = trisurf (tri, x, y, z, c2, "facecolor", "interp", "edgecolor", "k");

Gnuplot is able to produce the colored triangulated patches, but the coloring
isn't correct.
