This comment may cause confusion because it makes selection bounds sound like in
a different coordinate space from the rest, when they're not.  So I'd prefer it
wasn't added.

DIP and CSS pixels are basically the same thing.  Even zoom-for-dsf mode will
not change that as I understand it, and there are no medium-term plans to change
Android to zoom-for-dsf new mode anyway.

where CSS*mPageScaleFactor==DIP (and DIP*mDeviceScaleFactor==PHYSICAL)
Well, not exactly, I guess I forgot that terminology distinction (which probably
I wrote myself years ago).  Anyway, my main point is that I don't want us to add
a special comment referring to selection bounds when it's in the same space as
everything else.
