int spSkeletonBounds_aabbContainsPoint	(	spSkeletonBounds *	self,
		float	x,
		float	y
	)

Returns true if the axis aligned bounding box contains the point.

int spSkeletonBounds_aabbIntersectsSegment	(	spSkeletonBounds *	self,
		float	x1,
		float	y1,
		float	x2,
		float	y2
	)

Returns true if the axis aligned bounding box intersects the line segment.

int spSkeletonBounds_aabbIntersectsSkeleton	(	spSkeletonBounds *	self,
		spSkeletonBounds *	bounds
	)

Returns true if the axis aligned bounding box intersects the axis aligned bounding box of the specified bounds.

spBoundingBoxAttachment* spSkeletonBounds_containsPoint	(	spSkeletonBounds *	self,
		float	x,
		float	y
	)

Returns the first bounding box attachment that contains the point, or null.

When doing many checks, it is usually more efficient to only call this method if spSkeletonBounds_aabbContainsPoint returns true.

spPolygon* spSkeletonBounds_getPolygon	(	spSkeletonBounds *	self,
		spBoundingBoxAttachment *	boundingBox
	)

Returns the polygon for the specified bounding box, or null.

spBoundingBoxAttachment* spSkeletonBounds_intersectsSegment	(	spSkeletonBounds *	self,
		float	x1,
		float	y1,
		float	x2,
		float	y2
	)

Returns the first bounding box attachment that contains the line segment, or null.

When doing many checks, it is usually more efficient to only call this method if spSkeletonBounds_aabbIntersectsSegment returns true.
