[android-developers] Re: Mirroring a RelativeLayout

I want to flip the canvas _after_ all subviews are rendered, so that
the entire view is mirrored. That's why I put the transform after the
super. I do admit that is not based on actual knowledge how this stuff
really works. (by the way, the same function on iOS requires only a
single line of code!)

I sent you the screenshots via email... Hope that isn't violating the
group code.
