I gave this a quick look. The new input/output format appears to work
well. The input format using two points still works, which is nice.
Regression tests pass. I tried binary input and output using COPY and
it seems to round-trip without problem.
With the two-point input, horizontal and vertical lines can accept NaNs
without producing a NaN in the output if not necessary.
I tried "interpt" and "intersect" functions and they seem to work.
Haven't gotten around to trying other functions or operators.
