can we remove CCLayerImpl::contentsScale then?

Maybe we shouldn't have layer->contentsScale at all, and setContentsScale should setContentBounds, where appropriate?

I mean, contentsScale on LayerChromium makes sense as a hint to help create the contentBounds (tho maybe we should push that down to GraphicsLayerChromium)? But I think we should remove it from CCLayerImpl again if we can now, we plumbed it thru just for this code which is now going away here.

Or.. ya I get what you mean now.. that sounds like it could be very nice.

Yeah, removing it from the LayerChromium side *sounds* nice but is way more complicated.  Punt!
