/**
* @class vtkCocoaGLView
* @brief Cocoa OpenGL rendering context
*
*
* This class is a subclass of Cocoa's NSView; it uses Objective-C++.
* This class overrides several NSView methods.
* To provide the usual VTK keyboard user interface, it overrides the
* following methods: acceptsFirstResponder, keyDown:,
* keyUp:, and flagsChanged:
* To provide the usual VTK mouse user interface, it overrides the
* following methods: mouseMoved:, mouseEntered:,
* mouseExited: scrollWheel:, mouseDown:, rightMouseDown:,
* otherMouseDown:, mouseDragged:, rightMouseDragged:, otherMouseDragged:,
* and updateTrackingAreas.
* To be able to render and draw onscreen, it overrides drawRect:.
*
* Compatibility notes:
* - this class was previously a subclass of NSOpenGLView,
* but starting with VTK 5.0 is now a subclass of NSView.
* - starting with VTK 6.3 this class overrides the more modern
* updateTrackingAreas instead of resetCursorRects.
