BKE_mesh_validate is called by mesh.validate() Python API, as well as optionally when doing file imports. This PR speeds it up a bit: - Faster face data sorting by using parallel sort instead of qsort, - One allocation for all face vertex indices, instead of a separate allocation for each face, - (more like a fix) Validation no longer adds a MDeformVert layer when there was none in the input mesh. - Small cleanups (more const inputs, etc.) On my Windows/VS2022/Ryzen5950X machine, import time in seconds (validation on before this PR -> validation on with this PR, validation off): - USD (Intel Moore Lane): 9.1 -> 6.7, 4.8. - OBJ (Blender 3.0 splash): 22.7 -> 18.6, 16.5.
