debugger no longer sends play, pause notifications to the gui. the gui polls for that information as required govern package now has SubState type to complement the State type. StateIntegrity() function enforces combinations of State and SubState, called from debugger.setState() function playmode notifications reworked and contained in a single playmode_overlay.go file. this includes the FPS and screen detail preference value sdlimgui.playmode.fpsOverlay replaced with sdlimgui.playmode.fpsDetail. still toggled with F7 key coproc icon moved to top-left corner of playmode overlay and only visible when FPS detail is showing when FPS detail is showing multiple (small) icons care shown. when it is not showing, a single (large) icon is shown according to the priority of the icon. eg. pause indicator has higher priority than the mute indicator
