Add equal data aspect ratio to gnuplot graphics toolkit 3D plots (bug #47974). * axis.m: Clarify meaning of 'square' and 'equal' in documentation. Remove gnuplot-specific FIXME. * __gnuplot_draw_axes__.m: Remove line of cruft for sz_str. If the plot is 3D and data aspect ratio is equal in at least x-y dimensions, then set view equal.
