Implements the following: - Sequences have pixel aspect ratios that work in tandem with footage PARs to render footage correctly. Viewer and export also acknowledge PARs - Sequences can have interlacing settings. This doesn't do anything yet, eventually the renderer will need to interlace/deinterlace/reinterlace appropriately in order to conform all the footage to the sequence. Export acknowledges interlacing, but this only affects metadata, not the image.
