Hey there, while developing extensions I've found quite a lot features that are not available in the Flash runtime, but can easily be implemented.
For Add and Subtract, you can use DisplayObject.blendMode.
Set it to BlendMode.ADD or .SUBTRACT.
For Invert, use DisplayObject.transform.colorTransform.
There is an offset and multiplier member for each color channel (e.g. redMultiplier, greenOffset).
So just set all multipliers to -1 and all offsets to 255.
For Monochrome you could use a ColorMatrixFilter but it might be overkill.
Not sure about the bitwise ones.
Scaling SWF applets
I really don't get this one.
Just set stage.scaleMode to e.g. StageScaleMode.EXACT_FIT, and you can resize your SWF in HTML and it will automatically scale.
