======

   Each graphic object type have different default fonts fixed by
resources for the four label types of the fc2 format (struct, behav,
logic, hook). Example of resources for box label font :

       atg*behavLabelBoxFont: *-helvetica-bold-r-normal--12-*
       atg*structLabelBoxFont:*-helvetica-bold-r-normal--12-*
       atg*logicLabelBoxFont: *-helvetica-bold-r-normal--12-*
       atg*hookLabelBoxFont:  *-helvetica-bold-r-normal--12-*

   Corresponding to the screen fonts, each graphic object type have
postscript fonts also fixed by resources for the four label types of
the fc2 format (struct, behav, logic, hook), like :

       atg*behavLabelBoxPostscriptFont:  Helvetica-Bold 12
       atg*structLabelBoxPostscriptFont: Helvetica-Bold 12
       atg*logicLabelBoxPostscriptFont:  Helvetica-Bold 12
       atg*hookLabelBoxPostscriptFont:   Helvetica-Bold 12

   Label font can be changed by the <Attributes>:<Font> menu (you can
change font individually or on the selected sets of objects
altogether). This menu is fixed by resources. You give the number of
fonts you want to appear in the menu and you give the list of the
fonts together with its corresponding Postscript font.
   The <Font>:<Default> menu command is used to reset the original
font on the label.
