just preparing for a bigger change... introduced a global font (just one), it is lower case per default. I intend to modify the function for registering the default xpm to something accepting the 64x64 bitmap (application dependent) and insert it into the global pixmap. an other function could be used to register the alfabet pixmap and correspondently setting the variables indicating the position of each character. we would only support monospace alfabets. the 'printing' functions would also be simpler (less arguments), since it would be the library knowing which is the alfabet in use.
