The operand kinds form namespaces for their enumerants (only BitEnum and ValueEnum operand kinds are supported for this). Now `Lod` and `Bias` use `ImageOperands.Lod` and `ImageOperands.Bias`, which is probably a big improvement in the long run. Finally, all of QF's shaders *compile*, though the spir-v is generally incorrect (capabilities etc), and the code gen may still be full of bugs.
