+// are found on the X server.  It tries to place the fonts into families

+// and to sort them so the first 4 in a family are normal, bold, italic,

+// and bold italic.

+

+// Bug: older versions calculated the value for *ap as a side effect of

+// making the name, and then forgot about it. To avoid having to change

+// the header files I decided to store this value in the last character

+// of the font name array.

+#define ENDOFBUFFER 127 // sizeof(Fl_Font.fontname)-1
