I think in 1.7 you were getting a surface with no per-pixel alpha. 
therefore you could use .set_alpha() to change the alpha for the whole 
surface.

Now in 1.8 you are getting a surface with per-pixel alpha. That means 
that .set_alpha() will not work.

I know you can use .convert_alpha() to force a surface to have per-pixel 
alpha, but I don't know if there is any way to force a surface NOT to 
have per-pixel alpha.
