Memory/performance trading question?
What is the best?

I want to handle about 400 buttons (the buttons have 4 state).
What is the best? To store/display 4 different OPAQUE image for each button, or assamble the states from 2 ALPHA MASKED png?

I know that the question is a bit foggy.
More OPAQUE image, or less but ALPHA MASKED?

If there's any experience, please share.
