/**
 * Window on Mac OSX/Carbon.
 * Carbon windows have a size widget in the lower right corner of the window.
 * To force it to be visible, the height of the client rectangle is reduced so
 * that applications do not draw in that area. GHOST will manage that area
 * which is called the gutter.
 * When OpenGL contexts are active, GHOST will use AGL_BUFFER_RECT to prevent
 * OpenGL drawing outside the reduced client rectangle.
