This challenge is one of the reasons we're so excited about pcwalton's work on Pathfinder (https://github.com/pcwalton/pathfinder )

I'm ashamed to realize that despite being well aware of Pathfinder, and of Mozilla's somewhat surprising pivot toward "mixed reality", this connection had never occurred to me.

There's also Slug which handles variable-resolution shading of text (http://sluglibrary.com/), though it's unclear how its performance would stack up vs pathfinder's in these scenarios. IIRC when it was last discussed in this context it was unclear whether Pathfinder would work well for variable-resolution text that isn't screen aligned boxes?
