Which render/texture states are most often used for alpha-blitting? Which ones should I pay attention to? I've been able to get all sorts of cool alpha effects by playing with the blend modes, ADD vs MODULATE, etc... but I don't want to spend time playing with everything.

Any hints? Something like "Use ___ and ___ for color-additive blits," or "make sure you turn off ___ if you want to do ___."
