\page p_mask2 Mask2

The Mask2 type represents an aggregate of two true or false conditions.  You can think of the
Mask2 type as representing an array of two boolean values.  The math library has comparison
functions that generate Mask2 results.  For example, you can compare two Vector2 types to generate
a Mask2.  Mask2's may also be used to "select" between Vector2 objects.  This
ability allows "conditional" code to be written that does not contain any branch
instuctions.
