color_equal()

bool color_equal	(	struct color const	a,
		struct color const	b
	)

Return true if a and b represent exactly the same color.

Two structs that represent the same color might not be the same bits because the spec allows "padding" needed to satisfy alignment to contain any value.

  return (a.red == b.red) && (a.green == b.green) && (a.blue == b.blue);
