Multi-threaded software skinning by splitting the mesh up into batches of 10,000 vertices, which results in 27 jobs being spawned and executed using a character asset from a customer having 262,676 vertices and a speed improvement of 12x on a 32-core machine.
Single-threaded: 11,61 ms
Multi-threaded (27 jobs): 0,96 ms
* Created a SkinRange() function that can skin a part of the vertices.
* The actual skinning is now using the job system to split up the skinning into several pieces and executes them in parallel.
* Ported the bone info array to AzCore.
* Fixed some issues with the mesh based bounds update in the actor instance.
