A wxScreenDC can be used to paint on the screen. This should normally be constructed as a temporary stack object; don't store a wxScreenDC object.
When using multiple monitors, wxScreenDC corresponds to the entire virtual screen composed of all of them. Notice that coordinates on wxScreenDC can be negative in this case, see wxDisplay:getGeometry/1 for more.
