		const Matrix4x4 *	worldl = `null`,
		const Matrix4x4 *	worldm = `null`
	)

Generic collision query for generic OPCODE models. After the call, access the results:

Parameters

cache	[in/out] an lss cache
lss	[in] collision lss in local space
model	[in] Opcode model to collide with
worldl	[in] lss world matrix, or null
worldm	[in] model's world matrix, or null

Returns: true if success

Warning: SCALE NOT SUPPORTED. The matrices must contain rotation & translation parts only.
