◆ ED_transform_snap_sequencer_to_closest_strip_calc()

bool ED_transform_snap_sequencer_to_closest_strip_calc	(	Scene *	scene,
		ARegion *	region,
		int	frame_1,
		int	frame_2,
		int *	r_snap_distance,

Iterates over all the strips and finds the closest snapping candidate of either frame_1 or frame_2. The closest snapping candidate will be the closest start or end frame of an existing strip.

Returns: True if there was anything to snap to.
