All output falls under the domain of a font group. There
are 5 default font groups:
a axes
f figures and legends
l labels
p plots
t x, y, and graph title
These font groups can be modified, or new font groups can be
created using the `sf' option. Note that each font group
contains a field (gelem) which tells what part of the graph
it belongs to. This field is not used by plt, but can be used
it the plot driver if it wants to handle certain parts of the
graph differently. The default value of gelem is the name of
of the font group.
