When I looked at this last, i was thinking we had one too many conversions
between data types going on here, once you consider impl side painting. I was
thinking of just passing wgma struct up the renderer client. We only needed the
managed memory policy in old modes, and in impl side painting, we could then
make the tile manager use those wgma types and enums directly...

[observation: we want to move the memory manager callbacks to the output surface
anyway, right? We'd need memory managment in non3d and delegate dmodes...
sharing types is probably useful. And possibly related, output surface might be
easier to set up to use chrome types and avoid the whole web type nightmare]
