Use a wx.ScrolledWindow instead of a wx.Panel, and then set the virtual 
size of the wx.ScrolledWindow to the size of the image you want to 
display, and reset the virtual size when you want to zoom/unzoom.  If 
the virtual size is larger than the physical size then the scrollbars 
will automatically appear and allow the user to scroll.  You can use a 
wx.StaticBitmap to display the image, but in this case you'll probably 
be better off just drawing it yourself in a EVT_PAINT handler for the 
scrolled window.
