CSSMatrix and transform3d are a good start. A method returning a CSSMatrix object may be enough.

The following would help me to track elements and mouse clicks:

CSSMatrix getMatrixFromBounds(x,y,[optional] width, height)

1. Use the canvas width and height as the limits, 2, return a css matrix.

The author is responsible for using the matrix to translate points.
