-- Implementation of OnEraseBackground.
+- Implementation of OnEraseBackground. How? Call OnEraseBackground
+  just before OnPaint? Will duplicate Xlib's own erase of the background.
+  However, this is usually OK, because the default wxWindow::OnEraseBackground
+  can do nothing (SetBackgroundColour will make the background look OK).
+  And if a custom OnEraseBackground uses the same colour as the window
+  background, no flicker will be seen. If it does something else, such as
+  painting a tiled bitmap, then a slight flicker might be seen unless
+  X can be persuaded not to repaint the window background by default.
