pamstretch-gen - use pamstretch and pnmscale to scale by non-integer values
is a program which uses
to smoothly scale up a PNM file by any ratio; it's like a more general
version of pamstretch (hence the name). But other than the `any ratio'
bit, it's much the same as pamstretch. :-)
Uses awk just to make some simple floating-point calculations, which
is probably overkill. But using dc makes my head hurt.
