Importantly, I think this is going to replace my half-formed plan for an OSD (on screen display), which I'd envisioned as kind of a WinAmp-like metal bar that'd slide up to show things, but.... snazzy animated textured text seems more fun.

My plan, and I'm not sure if this is strictly necessary, is to stake out zones on a single canvas and render different text elements to them, then largely have the shader sort out what needs to be where.
