Look like smokris set it up to use CGColorSpace, which is probably smart and
pragmatic, by making a method ala:
CGColorRef CGColorWithNSColor(NSColor *nsc)
{
CGFloat components[4];
[nsc getComponents:(CGFloat *)&components];
return (CGColorRef)CGColorCreate([[nsc colorSpace] CGColorSpace],
components);
}
