But since you have to write your self_made_drawing_texts_func() in
any case, why not just always use this no matter what the VESA driver
reports? I think that is better than using the BIOS text printing
routines, for several reasons:

- Much faster.

- Allows you to draw text anywhere you like, rather than only on
integer character boundaries, so you can do smooth pixel scrolling.

- Easier to control the color of the text.

- Avoids problems with different DOS versions having different
character sets, depending on the country (if you supply the font,
you can always be sure the characters will come out looking as you
expect).
