Rendering Mapbox vector tiles

[robhawkes]

There are a lot of cool things you can do with Mapbox vector tiles (like visualising elevation and hillshading). I'd like to look into the feasibility of supporting Mapbox vector tiles as an input format.

Specific things to look into:

• What needs to be done to read the vector tiles?
• What aspects of the vector tiles should we support (text labels, elevation, etc)?
• How can they be visualised within the Three.js environment?
• Is this something that requires shaders instead of basic meshes (eg. rotating text labels, etc)?
