Changes: -Added support for custom inertia and center of mass in 3D -Added support for custom center of mass in 2D -Calculated center of mass from shapes in 2D (same as in 3D) -Fixed mass properties calculation with disabled shapes in 2D/3D -Removed first_integration which is not used in 2D and doesn't seem to make a lot of sense (prevents omit_force_integration to work during the first frame) -Support for custom inertia on different axes for RigidBody3D
