------- Additional Comments from Darin Adler <darin at apple.com>
Looks good.

+    float alpha = static_cast<float>(a) / 255.0f;

The cast above seems unneeded.

+		 c.setRGB(238, 238, 238); // FIXME: if this is a constant it
should be specified as one.

I agree that would be nice to fix, but I don't think the FIXME adds much.

+    const double scaleFactor = nextafter(256.0, +0.0);

I think the use of + here on +0.0 is a bit queer. We could have + in front of
all our floating point constants but we don't.

Looks good, those are minor quibbles. r=me
