Rect decimal precision

[Philippe Hurbain]

the rects and how to treat them seem to cause some skub:

I think the main cause (of manually done ones) is when they end on some external geometry (like partial/rotated cylos) or at intersections...
if these have bad/odd/unnecessary decimals, rectifying it can worsen things.
(because a rect is at half of the distance, if this is odd, the result will have one decimal more...)

Yes, that's part of the problem.
Moral of the story, use Rectifier carefully if you mind small vertex mismatches (which is generally NOT a problem at all!)
