François 9d54f33974 Skinned extraction speedup (#4428) ... # Objective - While animating 501 https://github.com/KhronosGroup/glTF-Sample-Models/tree/master/2.0/BrainStem, I noticed things were getting a little slow - Looking in tracy, the system `extract_skinned_meshes` is taking a lot of time, with a mean duration of 15.17ms ## Solution - ~~Use `Vec` instead of a `SmallVec`~~ - ~~Don't use an temporary variable~~ - Compute the affine matrix as an `Affine3A` instead - Remove the `temp` vec | |mean| |---|---| |base|15.17ms| |~~vec~~|~~9.31ms~~| |~~no temp variable~~|~~11.31ms~~| |removing the temp vector|8.43ms| |affine|13.21ms| |all together|7.23ms|		2022-04-07 16:16:36 +00:00
