Support complex matrices in Image image filter

Instead of using drawImageRect from fSrcRect to a dst rect already
mapped by the CTM, this concats the CTM to the intermediate canvas and
then does a drawImageRect from fSrcRect to fDstRect.

It also updates the passthrough optimization to require positive scale
factors so that mirrors aren't accidentally ignored.
