		between its two dynamic friction coefficients is greater).

		The anisotropy direction of the chosen material is transformed to world space:

		dirOfAnisotropyWS = shape2world * dirOfAnisotropy

		Next, the directions of anisotropy in one or more contact planes (i.e. orthogonal to the contact normal) have to be determined. 
		The two directions are:

		uAxis = (dirOfAnisotropyWS ^ contactNormal).normalize()
		vAxis = contactNormal ^ uAxis

		This way [uAxis, contactNormal, vAxis] forms a basis.

		It may happen, however, that (dirOfAnisotropyWS | contactNormal).magnitude() == 1

		solver is only an approximation, the result of the friction calculation can include a small
		"error" - e.g. a box resting on a slope should not move at all if the static friction is in
		action, but could slowly glide down the slope because of a small friction error in each 
		simulation step. The strong friction counter-acts this by remembering the small error and
		taking it to account during the next simulation step.

		However, in some cases the strong friction could cause problems, and this is why it is
		possible to disable the strong friction feature by setting this flag. One example is
		raycast vehicles, that are sliding fast across the surface, but still need a precise
		steering behavior. It may be a good idea to reenable the strong friction when objects
		are coming to a rest, to prevent them from slowly creeping down inclines.

		Note: This flag only has an effect if the MF_DisableFriction bit is 0.

	Joint projection is a method for correcting large joint errors. Joint errors occur when a joint's constraint is violated - imagine the ball being pulled out of the socket in a spherical joint. Under normal circumstances, joint errors are small yet unavoidable due to the imprecise nature of floating point math and numerical integrators. The SDK applies minimal correcting forces to the simulation to try and reduce joint errors over time.
	However, if a joint error becomes very large, more drastic measures are necessary, such as joint projection. The SDK can, in some situations, project (or change) the position of objects directly to fix the joint error. But when projecting the joint it is not desirable to completely remove the joint error because the correcting forces, which also affect velocity, would become zero.
