This is a "feature" of the window manager, rather than wx. In Windows, 
and in a lot of *nix window manager, you can set a property that sets 
whether you want the contents of Windows to be displayed as they are 
re-sized. However, you have to set it system-wide, not just for a 
particular app.

If you have an app that takes a while to Paint, it gets pretty ugly. The 
solution is to set (and re-set) a timer in EVT_SIZE, and only re-paint 
when the timer completes.

This is done in wx.lib.floatcanvas, if you want a sample. It's pretty 
easy really. but sure feels like a Kludge.
