Subject: Restore the possibility to construct FLTK objects and draw them
 within static initializers (which run before main() begins in an uncontrolled
 order). This was failing because calls to drawing functions (e.g.,
 fl_font(f,s);) crashed due to uninitialized fl_graphics_driver global
 variable.
