Allow auto screen size for LODs to be over 1. This is required for high poly meshes where simplifying causes only a small deviation.
...
Change mesh simplifier settings to match closer to what they used to be to prevent large changes in LOD distances from ue4 to ue5.

External edges now handle non-manifold meshes, ie multiple adjacency
...
Added Moore-Penrose pseudo inverse for solving singular quadrics. Disabled for now.

Replace Nanite coarse proxy mesh constant min number of vertices with a target simplification error and range. This allows it to allocate more triangles towards complex meshes and less towards simple ones, greatly improving complex proxy quality without changing memory budget.

Fix simplifier crash due to duplicate triangles. There were so many that a single edge collapse removed >100 triangles. Now checks for duplicates after every collapse so they don't accumulate.

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.
