Fix flaw in mozCurrentTransform polyfill

Browse source 
Set transformation matrix in (polyfilled) mozPrintCallback when a scale
is applied. Removed _scaleX and _scaleY in favor of _transformMatrix to
emphasize that the caller MUST ensure that the state of the matrix is
correct before `addContextCurrentTransform` is called.
