+ * The coding scheme for the different characters in .pk files in general are
+ * not stored in ascending order of the ascii value of the character. Access
+ * to an individual character would need a lot of searching within the
+ * pk buffer. So it is wise, to make a directory for all of the characters
+ * in the .pk font which holds a pointer to the flag byte for each of the
+ * characters when the pkfont is loaded the first time. These pointers are
+ * relative to 'pkbase' and stored into '(cbase + c)->pk_char' of the
+ * corresponding 'font'.
