I think it would solve the problem if we just draw to a memoryDC 
first, and then blit to the window when the paint event is requested.  
I believe the Buffered classes in 2.5 just make is slightly simpler 
to draw, but coding up one of those classes would be pretty easy as 
far as I can see.  You'd create a class that makes a wxMemoryDC in a 
constructor and writes to that.  Later, the destructor would blit the 
resulting bitmap to a wxClientDC.
