/**
@file Misc
@class Movie
The Movie object represents an opened MPEG file.
You control playback similar to a @Sound object.

Movie objects have a target @Surface.
The movie is rendered to this surface in a background thread.
If the surface is the @DisplaySurface,
and the system supports it,
the movie will render into a hardware YUV overlay plane.
If you don't set a target surface,
it will default to the DisplaySurface.

Movies are played back in background threads,
so there is very little management needed on the user end.
Just load the Movie, set the destination, and @play

<b>This is not usable yet</b>
