Details:

The OpenGL renderer is incorrectly using the z-argument of
"plotboxaspectratio" for 2-D drawings where it does not apply.

Sample code to reproduce:


t = linspace (0, 2*pi, 100);
y = sin (t);
plot (t, y);
axis equal
## This line causes plot to disappear
pbaspect ([1500 750 1])


The pbaspect command is merely calling for a 2:1 ratio.  The plot can be made
to re-appear by ensuring that the Z-argument is of the same order of magnitude
as the X and Y arguments.  Either of these work


pbaspect ([1500 750 750])
pbaspect ([2 1 1])
