-Currently we are limited to 256 symbols per font. We use a menu system with 5 lines, on a display with 64 pixel height. That means we have 12 pixel for a line. To have some space in between the lines we can't use more than 10 pixel height for the symbols. For up to 11 pixel set TALL_FONT_CORRECTION 1 when loading the font.
-To fit 22 Symbols on the 128 pixel wide screen, the symbols can't be wider than 5 pixel, for the first 128 symbols.
-For the second half of the font we now support up to 11x11 pixel.

- * Get 'Fony.exe'
- * Copy one of the existing *.fon files and work with this.
- * Change the pixels. Don't change width or height.
- * Export as *.bdf

- * Edit the produced .h file to match our needs. See hints in 'README.fonts' or the other 'dogm_font_data_.h' files.
