EVENT PRECUTSCENE
EVENT_PRECUTSCENE is a Misc Event.
This event is fired before the cutscene frame is rendered. Used with startcutscene and ifcutscene.
RETURN is set to the current cutscene frame. If the cutscene is an ANM file, RETURN can be altered to change the current frame of the cutscene. However, in the case of IVF files, this is not possible.
