49655a8d62 Ray-caster: remove debug code 
Remove GPU code and uniforms that were used as scaffolding during
initial development, but have now been replaced by CPU analogues.

interaction.

b289d2d4c3 Distinguish odd layer counts in debug mode 
The low-curvature construction admits odd layer counts.

ab830b194e Use circles in triangle as low-curvature construction 
In the process, add a way to build a sphere by offset and curvature.

a4236a34df Ray-caster: dim the interior layers of spheres 
This seems to weaken the intersection disk illusion.

f148552964 Ray-caster: only draw the top few fragments 
This seems to increase graphics pipe use from 50--60% to 55--65%.

6db9f5be6c 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.

8fde202911 Ray-caster: drop unused depth-pair array 
This doesn't affect GPU performance noticeably, so benchmarks before and
after the change should be comparable.

3d7ee98dd6 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.

c04e29f586 Reduce the frame interval sample frequency 
At the higher frequency we were using earlier, the overhead from
updating the readout contributed significantly to the frame interval.

01c2af6615 Rotate and translate construction 
In the process, write code to make updates that depend on the time
between frames.

a40a110788 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.

ec48592ef1 Ray-caster: add a frame time monitor 
It's time to start optimizing. Frame time is easy to measure, and we can
use it to gauge responsiveness.

5e9c5db231 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.

c18cac642b 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.

b9587872d3 Ray-caster: don't bother clearing the screen 
The ray-caster triangles cover the whole viewport, so they'll completely
overdraw the previous frame.

766d56027c Ray-caster: move shaders to separate files

indentation and syntax highlighting.
