_______________________________________________________
Details:
The following script
x = linspace(-2,2);
[X,Y] = meshgrid(x);
contourf(X,Y,X.^2+Y.^2-1,[0,0])
displays a white ball in a coloured background for any colormap I tried but
colormap(gray), for which the background is white. For sure it was gray (as it
should, in matlab too) in some previous versions of octave.
