Remove FLASH_SUBTRACT blend mode.

We may resurrect it later, but leave it out for now, as the closest
thing we have to a spec:

http://www.kaourantin.net/2005/09/some-word-on-blend-modes-in-flash.html

claims that alpha values should be subtracted, whereas real-world flash
files indicate that they shouldn't.
