 How to integrate a new font:
-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 then 10 pixel height for the symbols.
-We use fixed width fonts. To fit 22 Symbols on the 128 pixel wide screen, the symbols can't be wider than 5 pixel. Maybe you can work with half symbols - two places in the charset will than build one wide symbol.
