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?
