scroggo@google.com 82ec0b00f3 Allow setting a scaleFactor in bench_pictures (and render_pictures). 
In TiledPictureRenderer and CopyTilesRenderer, do a postTranslate so
the translate is not affected by the scale factor.

Likewise, use clipRegion for tiled renderer so it will be
unaffected by the scale factor.

Respect the viewport for record, playbackCreation, and pipe renderers.
