 * Right this will take some explaining. This vertex matches one of the 64 byte vertex
 * structures that the PVR supports, with the following "adjustments" (aka, abuse of free bytes)

 * There are 8 unused bytes anyway, and we steal the 4 bytes of the offset color alpha channel
 * which we don't really need.

 * glSecondaryColor doesn't support an alpha channel, and it's unusual that you would need it
 * for the offset color. It's much more useful as a cache-friendly space for something else
 *
 * Normal is stored as X + Y, packed into half floats. Z is reconstructed (as normals should have a length of 1)
