\page p_mask3 Mask3

The Mask3 type represents an aggregate of three true or false conditions.  You can think of the
Mask3 type as representing an array of three boolean values.  The math library has comparison
functions that generate Mask3 results.  For example, you can compare two Vector3 types to generate
a Mask3.  Mask3's may also be used to "select" between Vector3 objects.  This
ability allows "conditional" code to be written that does not contain any branch
instuctions.
