Inheritance diagram for impeller::scene::ScaleTimelineResolver:

Public Member Functions
	~ScaleTimelineResolver ()
void	Apply (AnimationTransforms &target, SecondsF time, Scalar weight) override
	Resolve and apply the property value to a target node. This operation is additive; a given node property may be amended by many different PropertyResolvers prior to rendering. For example, an AnimationPlayer may blend multiple Animations together by applying several AnimationClips.
