Ray-caster: only draw the top few fragments
...
This seems to increase graphics pipe use from 50--60% to 55--65%.

Enlarge the test construction to six spheres
...
In debug mode, assign most of the color scale to even layer counts. Odd
layer counts are topologically prohibited, so we should rarely see bugs
severe enough to produce them.

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.

This properly reflects the modularity of the code, and it simplifies
indentation and syntax highlighting.
