btVector3 can be used to represent 3D points and vectors.
It has an un-used w component to suit 16-byte alignment when btVector3 is stored in containers. This extra component can be used by derived classes (Quaternion?) or by user Ideally, this class should be replaced by a platform optimized SIMD version that keeps the data in registers
