for scalar==float, tis faster to always to MIN and MAX, than to put an ELSE betwixt them.

    if (x < min) min = x; else if (x > max) max = x;

This expression forces the compiler to know if the min expression executed, and
insert a conditional jump before the max. Slow.

    if (x < min) min = x; if (x > max) max = x;

This version allows the compiler to emitt MINSS and MAXSS unconditionally, giving
us a loop with zero branches inside.
