-Two new wx.Bitmap factory functions allow you to create a wx.Bitmap
-directly from a data buffer.  The the buffer can be any Python object
-that implements the buffer interface, or is convertable to a buffer,
-such as a string or an array.  The new functions are: <ul>
-
-<li><b>wx.BitmapFromBuffer</b>(width, height, dataBuffer, alphaBuffer=None):
-Creates the bitmap from a buffer of RGB bytes, optionally with a separate
-buffer of alpha bytes.
-
-<li><b>wx.BitmapFromBufferRGBA</b>(width, height, dataBuffer): Creates
-the bitmap from a buffer containing RGBA bytes.
-
-</ul>
