	Some time ago I wrote a program that could scale an image up
	or down in size by inserting or thowing away pixels.  This
	was OK for my needs and I didn't know any other way to do image
	scaling.

	A short time ago I found a program (no source code, though) that
	also scales image files, but it uses a "color-space" scaling method
	which which does not result in the loss of color resolution or aliasing
	that images from my scaling program suffered from.

	Just what is color-space scaling and how does it work?  I can find
	nothing about it in the imaging/graphics books I have.
