GOData * gog_plot_get_axis_bounds (GogPlot *plot, GogAxisType axis, GogPlotBoundInfo *bounds);
Queries plot for its axis preferences for axis and stores the results in
bounds. All elements of bounds are initialized to sane values before the
query _EXCEPT_ ::fmt. The caller is responsible for initializing it. This
is done so that once on plot has selected a format the others need not do
the lookup too if so desired.
Caller is responsible for unrefing ::fmt.
