- Further touch-ups with displayPort_t handling. - CANVAS is a FEATURE now. - Device specific xxxCmsInit() are registered by device’s init, and called by CMS upon entry to menu. - Multiple display devices can be cycled by entering menu invocation command while in menu. - The menu invocation command is (was) changed to THR-Mid + YAW-Left + Pitch-Full to avoid collision with MWOSD menu invocation command. - More separation attempt.
