This approach is 5 to 20x faster than the existing version,
mostly by minimizing the number of back-and-forths, especially
in the vanilla JS Array case.

Using value_array (and value_object), while convenient,
adds a measurable overhead. This removes the Point value_object
and replaces it as a return value with Float32Array
(similar to rects). For inputs of a single point, I just
split it into x and y. For inputs with two points, I used
a _scratchFourFloats (formerly _scratchRect) bit of memory.
Two subtle decisions here:
- Why not use scratch memory for a single point? The cost of
having one extra param is a small/negligible price to pay
for less complex code.
- Why not accept Malloc objects? Again, simplicity. Accommodating
Malloc would make the code harder to read and require more
checks. I don't know if anyone wants to have malloced points;
if they do, we can probably accommodate that.
