Description

It would be great to have Photoshop style Blendmodes for drawing Images.

examples:
Multiply: http://graphicssoft.about.com/od/glossary/ig/Blending-Modes/Blend-Multip...
Negative Multiply / Screen: http://graphicssoft.about.com/od/glossary/ig/Blending-Modes/Blend-Screen...
Additive / Subtractive

This would be great for Particle Effects etc.

Im not sure if its already implemented (couldnt find it) and its probably a bigger task as, i think, it has to be implemented in all drivers. but it would be a great addition.

Yes, this is an excellent feature which has been in the back of my mind for a while. Most of the boilerplate code for this is already implemented, I just need to go and add the individual blend modes.
