Bitmap Fonts

I will try to use some common sense for spacing when converting the fonts. If characters like I, J, 1, and maybe some others, have serifs and try to extend to sides to cover some width around, I will tend to make the font non-proportional; and vice versa.
On the other hand, not every font has to be proportional; some fonts from games of the 8-bit and 16-bit era have letters like W and M 'minimized' to fit the width of every other letter - that, conversely, would be the indicator for me to keep the font non-proportional.
Simply put, I'll try to be more careful in deciding proportionality further on.
P.S. Don't hesitate to say or comment if you think some font should be proportional/non-proportional - I will listen.

I agree with you. For demo purposes it is easier to scroll text when every letter has the same size. moving byte multiples in memory is the way to minimize processing time. For BMFs, the requirements are different. Calculation time in no issue, and you don't have real-time concerns. So doing the "proportion treatment" is certainly improving readability. It requires more work for you, though...

@Zbeng: Yeah, I made it non-proportional. You think all characters should have a fixed width (or "shift")? Yes, the image of the font would suggest that - all characters are arrayed in constant distances - but I think that doesn't have to be the case necessarily. For example, the letter "I" doesn't have serifs up and down (like Courier, e.g.) trying to gain some additional width; to me that indicates the typography counts with proportional layout. And yes, the usage of the font in appropriate intro or demo in which it was used might have treated it as non-proportional (for simpler computation of each letter's position), but again, the origin of it (the Ming font, or the "Terminator 2" font of which it was inspired) are both proporitonal. In addition, text like, e.g. "HIM" would create weird gaps around "I" if it were non-proportional. It just doesn't look and feel right to me.
What do you think?
