SDL additive alpha? Multiplicave alpha?

[SJ Zero]

I'm curious to know if the alpha support included in SDL is the only alpha mode supported. Blending is nice and all, but I want my explosions to be brighter, not dimmer!

ah try blending a white surface on top of the surface you want to brighten.

that should make the surface with the image you want to brighter RGB value match closer to plain white well depanding on the alpha value you used
