* a best effort fix for apps that uses get/set Matrix API on canvas.

  - scale the matrix
  - but don't scale if the matrix *looks* like obtained from the canvas itself. (typically to set it back to original matrix)

This is best effort change and not perfect (not even close), but works for one game,
and hopes it can handle many other apps that uses set/get Matrix. If you have an alternative idea, please let me know.
