- It can be used in the same way as any other device context.
- wx.BufferedDC itself typically replaces `wx.ClientDC`, if you want to
- use it in your EVT_PAINT handler, you should look at
- `wx.BufferedPaintDC`.
-
- Please note that GTK+ 2.0 and OS X provide double buffering themselves
- natively. wxBufferedDC is aware of this however, and will bypass the buffering
- unless an explicit buffer bitmap is given.

- flicker. The only thing to watch out for is that if you are using this
- class together with `wx.ScrolledWindow`, you probably do **not** want
- to call `wx.Window.PrepareDC` on it as it already does this internally
- for the real underlying `wx.PaintDC`.
-
- If your window is already fully buffered in a `wx.Bitmap` then your
- EVT_PAINT handler can be as simple as just creating a
- ``wx.BufferedPaintDC`` as it will `Blit` the buffer to the window
- automatically when it is destroyed. For example::
-
- def OnPaint(self, event):
- dc = wx.BufferedPaintDC(self, self.buffer)
