Yuck :-)

Besides, ANSI says nothing about the size of a double versus the size of 
other types. Some platform may have sizeof(double)<8.

Also, IMHO whatever type we are using, it should be straightforward to 
extract r,g,b components from it, without typecasting.

I also think that an optimizing compiler might get confused and put it 
in a floating point register, making it much slower.

I think that the best way to pass big size parameters is by a pointer to 
a struct.
