Comment (by nicklas):
I don't really get this request.
lwgeom_mindistance2d_tolerance is just an internal function with a bad
name.
raising the tolerance above 0 will stop the calculations to save some cpu-
cycles.
But the logic of ST_DWithin is done on the outer function LWGEOM_dwithin.
Testing if the function stops as expected I can understand, but the result
will change with small changes in code without changing output.
But where to document it? and for who?
