Although since all SCHEDULED* states basically have the same transitions
it's easier to show them as a single state. The mermaid diagram also won't
render correctly if there is a mix of combined and singular states. We
must use either always combined states or always singular states.

INIT --> SCHEDULED* : first frame scheduled
|
|
IDLE --> SCHEDULED* : next frame scheduled
|
|
SCHEDULED* --> IDLE : frame clock inhibited or mode changed
|
|
SCHEDULED* --> SCHEDULED* : schedule upgraded to SCHEDULED_NOW
|
|
SCHEDULED* --> DISPATCHING : the update time has arrived
|
|
DISPATCHING --> PENDING_PRESENTED : the update has been handed to the backend
|
|
PENDING_PRESENTED --> IDLE : frame was either presented or aborted with nothing to draw
