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: 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: only draw when the scene is changed
...
This is how I typically schedule draw calls in JavaScript applications.
The baseline CPU activity for the display prototype is now in line with
other pages (though perhaps a bit higher), and the profiler shows little
time being spent in draw calls, even when I'm continually moving a
slider. The interface feels pretty responsive overall, although the
sliders seem to be lagging a bit.

Ray-caster: switch from draw effect to animation loop

This wastes a lot of CPU time, as explained on lines 253--258 of
`main.rs`, but it's better than the previous version, which could block
graphics updates system-wide for seconds on end.
