I think you'll want to use the wxImage::Scale function [1], which is
exposed as imageScale in wxcore.

(I don't really remember the details here) It's useful to know that
wxHaskell has an automatically generated bit of Haskell from a C++ => C
wrapper. So if it's in wxWidgets, it may just be buried away in wxcore
somewhere [2], even if it's not exposed with a nice library function or
bubbled up in wx.

The scale function from the wxImage class is called imageScale (the
names are generated automatically: drop the wx, camel case, etc)...
