\page p_maskscalar MaskScalar

The MaskScalar type represents a true or false condition.  You can think of the
MaskScalar type as representing a boolean value.  The math library has comparison
functions that generate MaskScalar results.  MaskScalar's may also be used to
"select" between different data.  This ability allows "conditional" code to be
written that does not contain any branch instuctions.
