The NSViewGlobalFrameDidChangeNotification notification is documented to be fired every time [NSOpenGLContext update] needs to be called. However, the notification fails to fire on my setup when a window is moved to a display with a different pixel scale, which leads to incorrectly sized output. This change gets rid of the notification and updates the context before every frame. Signed-off-by: Elias Naur <mail@eliasnaur.com>
