<h2>BitmapButton</h2>

<p>A BitmapButton control displays a bitmap. It can have a separate bitmap for each button state: normal, selected, disabled.</p>

<p>The bitmaps to be displayed should have a small number of colours, such as 16, 
to avoid palette problems.</p>

<p>A bitmap can be derived from most image formats using the wx.Image class.</p>
