Details:

Run following code and compare with Matlab. I have attached also a screenshot
for comparison.

++
hax = axes ();
[xx, yy] = meshgrid (-20:.1:20, -20:.1:20);
r = sqrt ((xx).^2 + (yy).^2);
zz =  sin (r) ./ r;
surf (xx, yy, zz, 'edgecolor', 'none');
daspect ([1, 1, 1]);
hcb = colorbar;
get (hcb, 'position')
--

The Matlab output for "hcb" is

++
0.8338    0.1100    0.0381    0.8150
--

I suspect the code in "calc_cbar_position" around line 600 but haven't had a
closer look at this.
