/*
 Move everything here that manages the native window interface.

 There is one window driver for each Fl_Window. Window drivers manage window
 actions such as resizing, events, decoration, fullscreen modes, etc. . All
 drawing and rendering is managed by the Surface device and the associated 
 graphics driver.

 - window specific event handling
 - window types and styles, depth, etc.
 - decorations
 
 ? where do we handle the interface between OpenGL/DirectX and Cocoa/WIN32/Glx?
