I plan to add jittering to my patch eventually, it should be quite easy.

What? I don't know what you mean by "scale factor"...
My patch allowed you to specify the size of the matrix separate from the

That is the other method I was talking about. :-)
Basically, sample along each axis, possibly with anti-aliasing and/or
jitter.
