Bug Description

When standing far from the end points along an axis in which a selection extends largely on and looking along said axis, the lines rendered thicken (they become thicker the closer you get to the middle of the selection span). This occurs along any of the 3 axes. The larger the selection is, the thicker the lines become as well so it's not particularly noticeable on small selections.

Expected Behavior

I'd expect to see regular non-ultra thick lines

Reproduction Steps

1. Make a really large selection along any axis
2. Stand anywhere not near the end points of the selection on that axis
3. Look along that axis

Anything Else?
