Something that allows the use of tk scaling would be really nice. Then
you could scale the patch and everything would remain proportional.
This would be a really nice way to support all the varying screen
sizes, and it seem to be already built into Tk. It sounds like its a
matter of letting Tk do the box sizing. It'll already handle the fonts
fine if you switch to Tk-style font specs from Xwindows font specs.
