(just to nitpick, when you blow up an image, the pixels are interpolated,
not repeated. That's why it looks blury. Without anti-aliasing you do get
repitition. What gimp does (more or less) is a simple liniar interpolation
to find out what inbetween colors are. IE if you have a black box on white,
when you double the size you'll end up with a grey line between the black
and white because that pixel would map to between a black and a white
pixel.)

I think the ting to do is scale up normally, then use something like unsharp
mask to get some detail back. I remember seeing a link (perhaps from this
list) that was to information on unsharp mask and an even better shaprening
filter someone had made.
