## Conversions among wxImage, wxBitmap, wxCursor, wxIcon and DATA
##      wxImage to wxBitmap --  myWxImage.ConvertToBitmap() or wxBitmapFromImage(myWxImage) 
##      wxImage to DATA --  myWxImage.GetData()  returning a string in width * height * 3 format
##      DATA to wxImage --  image = wxImage(); image.SetData( data )  where data is a Python string of length width * height * 3.
##      DATA to wxBitmap -- Go through wxImage to get to wxBitmap.
##      DATA to wxIcon -- Should be possible, but I don't see an overloaded-constructor name for it.
##      wxIcon to wxBitmap --  bitmap = wxEmptyBitmap( icon.GetWidth(), icon.GetHeight()); bitmap.CopyFromIcon( icon )
