/* This file belongs to both libplot and libplotter. It contains a
function that appears in both the old (non-thread-safe) C and C++
bindings. It is named pl_parampl() and parampl(), respectively.
pl_parampl/parampl sets parameters in a global PlotterParams object,
which is used as a source of parameters when any Plotter is created.
The presence of this global state is one reason why the old API's are
not thread-safe.
In libplotter, parampl is a static function member of the Plotter class,
as is the global PlotterParams. This is arranged by #ifdef's in
extern.h.
In both libplot and libplotter, the pointer to the global PlotterParams,
which is called _old_api_global_plotter_params, is defined in
g_defplot.c. */
