I still think that we need a better "I have some externally-derived

times before), and the current imagedata design makes it very difficult
to use it correctly for this purpose...
It's not that hard, it's an extra four or five lines of code to fill in
multiple pixels in a square (two nested for-loops and an expression or two
to work out what the limit is). Compared to the maths such code would be
doing anyway, this is trivial stuff.
The hard part is realizing you have to do it...
