Patrick Walton 6c31e1bc01 In VR mode, render one eye and then reproject to both eyes instead of rendering 
twice.

This reduces both CPU and GPU time a lot in exchange for a small loss in
quality.

Patrick Walton c688d04412 Remove the scene assembly thread, and pipeline only fills instead of alpha 
tiles.

Removing a thread should make it easier to manually assign threads to CPUs, as
is necessary on devices with poor schedulers like Magic Leap 1.

Patrick Walton 224c8e85b9 Create separate shaders for monochrome and multicolor tiles. 
This is preparation for fixing subpixel AA.

Patrick Walton 26fea26f87 Allow construction of a `Transform3DF32` from a quaternion describing a 
rotation.

Closes #111.
