Rune Stubbe 9dbd92093b New Nanite vertex quantization code that replaces the cluster-relative coordinates with quantization to an absolute po2-sized grid centered around the mesh center. ...

The scheme solves issues where meshes would no longer align properly after converting them to Nanite. It also solves the precision issues in clusters with triangles of non-uniform size.
By default the precision is heuristically selected by Nanite, but the user also has the ability to override with an explicit precision to solve issues or optimize for disk size.
Clusters store the coordinate components using the minimal number of bits required to span the range of values in the cluster.
Apart from fixing issues, the default quality seems no worse than before and is typically ~5-10% smaller than before.

Added Position Precision to the top left of Mesh viewer along with the other mesh stats.
Added Position Precision dropdown to Nanite import settings.
Added debug mode "r.nanite.visualize PositionBits" that shows the vertex position bit sizes for clusters.
New quantization code now updates float positions and cluster bounds to reflect the quantized coordinates.
