copy a wxDC to wxScrolledWindow

[Piotr Starczewski]

That should not be a problem. First of all you need to get a 
pointer/reference to your source wxDC. Then just wxDC::Blit it into 
wxMemoryDC with selected bitmap. Final step is to rescale your bitmap 
and draw it with wxDC::DrawBitmap(...) onto your scrolled window.
