Sebastien Loriot d731405249 PMP: Fix slow compute_vertex_normal() (#8684) ... ## Summary of Changes For the testcase provided in this PR `compute_vertex_normal()` is particularly slow. A vertex has a fan of incident faces with identical normal. As the first fix tests with `operator==(Vector_3,Vector_3)` it is still slow when the object is slightly rotated or perturbed. With a bound on the angle between normals it is fixed, but is that acceptable? For `double` probably. Do we have to specialize for exact number types? ## Release Management * Affected package(s): PMP * License and copyright ownership: GF		2025-08-05 16:22:21 +02:00
