[gamut, badIndex] = PrimaryToGamut(cal,primary)
Check that primary coordinates are in range [0,1].
Force them to be so if not. The indices of the
out of gamut primary settings are returned as ‘badIndex’.

9/13/93 jms Took out the global flag and instead return
a flag vector for the ones that were changed.

I want to pass it through these routines generally
