-------------------------------------------------------------
This clause was added to the test alone, because the quantization can, in
theory, pull a point to a slightly different place, and therefore the test
(which bases its evaluation on the raw, unquantized point) can falsely claim
that the point should be in (when it shouldn't) or out (when it shouldn't).
Once the point is indexed though the quantized (x,y,z) *is* the benchmark, not
the raw unquantized value. Geo3D is correct either way -- it doesn't lie, it
tells you whether the point is on or out, period.
So what you are looking at is code explicitly for testing, nothing more.
[~mikemccand]: You wrote the test -- can you help clarify please?
