Subject: Simplify API for Fl_Image_Surface::Fl_Image_Surface(int w, int h, int
 high_res, Fl_Offscreen off) with non-null offscreen.

The caller no longer needs to call Fl_Image_Surface::get_offscreen_before_delete() before object deletion,
because the object destructor knows the offscreen has not been created by the Fl_Image_Surface constructor.
