* Split z64.h more * fix speedmeter.h (expect this kind of issue resolution to pop up eventually) * fix z64object.h * fix z64state.h * fix (probably only partially) z64play.h * fix fix speedmeter.h :) * revert making a play header (sadge), add/split transition & transition_instances * move stuff to cutscene, interface * Move `TransitionCircle%` enums to `z64transition_instances.h` * z64state.h -> z64game.h with a "this is not final" comment * forward declare GraphicsContext in z64game.h instead of including the header file for it * don't comment on where the forward declarations are from reasoning: 1) it's easy to go out of sync (like this comment, it was outdated anyway) 2) any IDE can easily find the struct anyway
