Right now it seems as if I will have to support both 565 and 555 mode 
anyway, using some global switch or so.

Nope, it won't be able to handle the alpha blending. How should it be 
able to do it when we only have one bit of alpha mask? So to be able 
to do it, I am right now doing the alpha blending in the old way 
(only change is that now we don't blend using a palette anymore).

We definitly want a ScummVM font that looks the same on all systems, aye.
