cc: Remove low quality mode and cleanup tile versions.

This patch removes low quality mode for low resolution tiles. It also
cleansup some logic with tile versions, since there's only one now.

As a follow-up we can see if we should move the tile version stuff
onto tile directly, although I kind of prefer having a separate class
just for managing what mode we're drawing.
