Overview = """\ A BitmapButton control displays a bitmap. It can have a separate bitmap for each button state: normal, selected, disabled. The bitmaps to be displayed should have a small number of colours, such as 16,
to avoid palette problems. A bitmap can be derived from most image formats using the wx.Image class. """
