More about scaled characters coordinates...

I must say, I'm not sure this is the best approach for mouse coordinates. I believe that natively, SDL returns everything as pixels, and as such, if we want to convert them (or not for that matter even in text mode) that should be left up to the developer. having pixel level coordinates in text mode would be great especially for those of us that like to create our own custom fonts though.

But even without that, I think that all mouse sub systems working on the same scales and letting the programmer define how to use that scale is a much better approach. I'm sure we could all find uses for both scaled and unscaled values even in straight text mode.
