Supported flags for Chaos filter, shares some flags with EPhysXFilterDataFlags Shared flags should be kept in sync until unified. LEGACY CODE Kept around for serialization of old data. Most of the API has been removed, except what is needed to convert to the new format. See ConvexHalfEdgeStructureData.h for the replacement.

This is an approximation but only collides with spheres in the velocity direction which can hurt compared to all directions when it comes to thickness

todo: -proper suspension setup for resting position - decide on parameters i.e. use SuspensionMaxRaise/SuspensionMaxDrop?? -natural frequency stuff -defaults

todo: Not really making use of this yet. Tire nuances more advanced than current simulation which just requires one friction value

todo: Add clutch option #todo: Proper defaults
