// the movie contained in the savestate will be loaded into memory
// the frames in the movie after the savestate frame will be discarded
// the in-memory movie will have its rerecord count incremented
// the in-memory movie will be dumped to disk as fcm.

Playback or Recording + Read-only
* Check that GUID of movie and savestate-movie must match or else error
o on error: a message informing that the savestate doesn't belong to this movie. This is a GUID mismatch error. Give user a choice to load it anyway.
+ failstate: if use declines, loadstate attempt canceled, movie can resume as if not attempted if user has backup savstates enabled else stop movie
* Check that movie and savestate-movie are in same timeline. If not then this is a wrong timeline error.
o on error: a message informing that the savestate doesn't belong to this movie
+ failstate: loadstate attempt canceled, movie can resume as if not attempted if user has backup savestates enabled else stop movie
* Check that savestate-movie is not greater than movie. If not then this is a future event error and is not allowed in read-only
o on error: message informing that the savestate is from a frame after the last frame of the movie
+ failstate - loadstate attempt cancelled, movie can resume if user has backup savesattes enabled, else stop movie
* Check that savestate framcount <= savestate movie length. If not this is a post-movie savestate
o on post-movie: See post-movie event section.
* All error checks have passed, state will be loaded
* Movie contained in the savestate will be discarded
* Movie is now in Playback mode
Playback, Recording + Read+write
* Check that GUID of movie and savestate-movie must match or else error
o on error: a message informing that the savestate doesn't belong to this movie. This is a GUID mismatch error. Give user a choice to load it anyway.
+ failstate: if use declines, loadstate attempt canceled, movie can resume as if not attempted (stop movie if resume fails)canceled, movie can resume if backup savestates enabled else stopmovie
* Check that savestate framcount <= savestate movie length. If not this is a post-movie savestate
o on post-movie: See post-movie event section.
* savestate passed all error checks and will now be loaded in its entirety and replace movie (note: there will be no truncation yet)
* current framecount will be set to savestate framecount
* on the next frame of input, movie will be truncated to framecount
o (note: savestate-movie can be a future event of the movie timeline, or a completely new timeline and it is still allowed)
* Rerecord count of movie will be incremented
* Movie is now in record mode
Post-movie savestate event
* Whan a savestate is loaded and is determined that the savestate-movie length is less than the savestate framecount then it is a post-movie savestate. These occur when a savestate was made during Movie Finished mode.
* If read+write, the entire savestate movie will be loaded and replace current movie.
* If read-only, the savestate movie will be discarded
* Mode will be switched to Move Finished
* Savestate will be loaded
* Current framecount changes to savestate framecount
* User will have control of input as if Movie inactive mode
