Brian Karis e1dab2c3a9 Fixed Nanite holes which were due to inversion penalty being scale only. When error is zero or near zero like an edge on a flat plane, triangle inversion is also likely and the penality for it doesn't help if it's a scale.
The reason why I switched from bias to scale was to put the penalities in the same relative spectrum of the collapses being considered. Degree should probably still be more like that but for now it's safer to just go back to what this was before.
