Multimatrix Tweener Component

The multimatrix tweener, of type kTweenTypeMultiMatrix , returns a MatrixRecord that is a concatenation of several matrix tweeners. This record can be applied to a sprite or track.

An example of using the multimatrix tweener would be to make a sprite follow a path using the path tweener and at the same time apply a distortion effect using the polygon tweener.

Input data: A list of kTweenEntry atoms.

Output data: a matrix record

How interpolation is performed: The data for the tweener consists of a list of kTweenEntry atoms, each containing [(QTAtomListEntryAtoms)] for any type of tweener that returns a matrix. The order of matrix concatenation is important; the matrices are applied in the order determined by index of the kTweenEntry child atoms of the multimatrix tweener's data atom.
