/*
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/Windows/Glx?
