1) The original nanosvg.h file is modified for FLTK in file fl_nanosvg.h. The only change is
to remove the implementation of function nsvg__atof().
2) FLTK provides an implementation of nsvg__atof() based on sscanf().
3) FLTK changes the LC_NUMERIC locale to "C" before calling nanosvg
and resets it to its previous state after.
