# SGI_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 SGI_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.
