I suppose you are correct.  However, I think we are left with the same 
trial-and-error-ish-ness.

PostScript doesn't have a size (or more appropriately BoundingBox) 
specification.  But still, what would be the difference of having to 
tweak the values in the PostScript file or at the "set term" line?  In 
the former case at least you can just modify the number and reload the 
PS file in Ghostview.  In the latter case one must continually reissue 
the plotting sequence of commands, then reload the PS file in Ghostview.

I just tried an example with the above PNG syntax.  With a color box on 
the right side, and the square image, and the 500 by 500 output, there 
remains whitespace now at the top of the image.

YES!!!!!!!!  Everything fine trimmed right up to the first non-white 
pixels.  Perfect.  Every terminal should have such an option.
