Chapter 273: MotionPathPlugin.convertCoordinates()

Core Idea

Converts a point from one element's local coordinate space into another element's local coordinate space, correctly accounting for any number of nested transforms on either element.

Reference Tables

Parameter	Type	Description
fromElement	Element | window	source coordinate space
toElement	Element | window	target coordinate space
point	Object (optional)	{x, y} in fromElement's space

Returns: the converted point (or a Matrix2D if no point is supplied).
