When calling trisurf with gnuplot toolkit with something like

> x = rand(100, 1); y = rand(100, 1); z = x.^2 + y.^2;
> tri = delaunay(x, y);
> graphics_toolkit('gnuplot');
> trisurf(tri, x, y, z);

it results in

error: __go_draw_axes__: operator *: nonconformant arguments (op1 is 0x0, op2
is 3x1)
error: called from:
error:   /workspace/LOCAL/OCTAVE/octave-3.4.0/scripts/plot/__go_draw_axes__.m
at line 649, column 30
/workspace/LOCAL/OCTAVE/octave-3.4.0/scripts/plot/__go_draw_figure__.m at line
167, column 19
/workspace/LOCAL/OCTAVE/octave-3.4.0/scripts/plot/__gnuplot_drawnow__.m at
line 86, column 5

This is new to 3.4.0, the 3.2.x series works as expected. Using trisurf with
FLTK toolkit in 3.4.0 also works as expected.

If this bug is fixed could you please add a test or demo in trisurf.m
performing the above sequence of commands for both backends.
