<pre>Orbital Explorer currently hangs the GPU when run with INTEL_SCALAR_GS=1. This
would need to be fixed before we could consider enabling the scalar backend by
default.
Also, it generates awful code: something on the order of 3x the number of
instructions, along with spilling. The vec4 code does not spill.
For reference, here's my fork of orbital explorer that uses waffle and builds
on Linux (the original was Mac OS X focused, and now unmaintained):
