Question Additive blending

[CodeImp]

I'd like to do additive blending of one image over another using the provided .NET graphics features. I have google'd it, but that turned it up with about 0 useful results. In fact, it seems like no-one even asked about doing additive blending with .NET at all!

So, is it so simple and obvious that no-one ever had to ask and I just totally missed it? Or is it impossible with .NET? Does anyone have any suggestions?

Aside from the fact that that demo doesn't even show additive blending; that demo performs blending manually (locking the images and doing the calculations). Sure I can do that, but that is like a last resort. What about .NET functionality? Don't tell me they have these fancy things like ColorMatrix but completely forgot about something as common as additive blending
