Title: Fix billboard and polyline jitter

This fixes jitter artifacts when zoomed in close to polylines and billboards by using RTE.

@pjcozzi wrote most of this, not me, though I'll fix any problems you see.

Some of this is pretty messy, especially the Columbus View / 2D / morph parts. We need to look hard at the architecture for those, but that's a separate pull request.

My changes to the `VertexArrayFacade` allow a subset of vertex attributes to be passed to the shader in different passes. This was necessary to keep the total number of attributes under 8, the number guaranteed by WebGL. This class could use some optimization, but I don't think I made it enormously worse, at least.
