+# CCP_FONT -- Set the character font.  The roman font is normal.  Bold is
+# implemented by increasing the vector line width; care must be taken to
+# set CCP_WIDTH so that the other vector drawing procedures remember to
+# change the width back.  The italic font is implemented in the character
+# generator by a geometric transformation.
