# GKT_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 GKT_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.
