Ray-caster: drop unused depth-pair array
...
This doesn't affect GPU performance noticeably, so benchmarks before and
after the change should be comparable.

Ray-caster: check layer count
...
In debug mode, show the layer count instead of the shaded image. This
reveals a bug: testing whether the hit depth is NaN doesn't actually
detect sphere misses, because `sphere_cast` returns -1 rather than NaN
to indicate a miss.

Ray-caster: generalize depth sorting
...
Switch from a hard-coded sorting network for four fragments to an
insertion sort, which should work for any number of fragments.
