Erm, well it appears that imageScale is wrapped by wxcore (I'm not sure how
familiar you are with wxHaskell?), so it *might* just work, see here:
http://hackage.haskell.org/packages/archive/wxcore/0.12.1.7/doc/html/Graphics-UI-WXCore-WxcClassesAL.html#g:105

There is a basic image view program here:
http://code.haskell.org/wxhaskell/samples/wxcore/ImageViewer.hs

So it might be fun so see if you can use imageScale easily with that, you
could even extend the sample code to provide zoom functionality and send a
patch back to the list :)

Good luck,
Dave
