Bug in 3d-distance functions

[nicklas]

This gives right answer: POINT(0 5 3)

select st_asewkt(st_3dclosestpoint(
'POLYGON((0 0 0,0 0 5,0 10 5,0 10 0, 0 0 0))'::geometry, 
'POINT(5 5 3)'::geometry))

But this gives wrong answer POINT(5 0 5) instead of POINT(5 0 3)

select st_asewkt(st_3dclosestpoint(
'POLYGON((0 0 0,0 0 5,10 0 5,10 0 0, 0 0 0))'::geometry, 
'POINT(5 5 3)'::geometry))

It finds the closest distance when checking against the boudary instead of against the surface. And as shown above it is not consistent.

I will take a look soon.

Fixed in r6580

with r6580, you changed a function on line 1072 from fabs() to abs() .. you might want to put this back to fabs()

Thanks mwtoews, fixed in r6583
