Same comment applies to the naming in LayerFragment. mstensho (USE GERRIT) 2014/11/14 08:18:48 Done. Yeah, paginationOffset isn't a great name.

Yeah, paginationOffset isn't a great name. I'd be tempting to call it fragmentTranslation, or at least something with translation. Because that's what it is. It's the translation required to get from flow thread coordinates to visual coordinates. I'll use fragmentOffset here for now, and get back to the big rename at a later time.
