\page p_vector_3_plus Vector3Plus

The \c Vector3Plus type is essentially used only for storage purposes.  On the
VPU, all \c Vector3's are actually padded out to 4 elements to preserve
vector alignment.  That means that each \c Vector3 is wasting 4 bytes of memory.
For some applications, it is useful to interleave other useful data with Vector3's.
Therefore, the library provides the \c Vector3Plus type for storing Vector3 data
plus an additional scalar element.
