+SPIR-V.  The goal is to emit GLSL or MSL that looks like it was written by a
+human and not awkward IR/assembly-like code.  NOTE: Individual features are
+expected to be mostly complete, but it is possible that certain obscure GLSL
+features are not yet supported.  However, most missing features are expected
+to be \"trivial\" improvements at this stage.")
