Detailed Description

4 dimensional floating point vector

This 16 byte vector contains x,y,z and w 32 bit floating point coordinates. A set of common functions for simple 4 dimensional math are part of the structure.

It is expected to be 4 byte aligned and use scalar math. The members are hard coded to be "x", "y", "z" and "w" for maximum compatibility

Note: Since this is a structure, there is no constructor or destructor, so assume the data is uninitialized when creating this data type.
