Fix use of several FLTK widgets above an GL scene.
The code failed with 2 or more widgets when FLTK would trigger
partial redraws of the widgets, unless the Fl_Gl_Window was FL_DAMAGE_ALL.
This commit also adds a second FLTK widget to example/OpenGL3test to
check this multiple widget situation, and fixes an error where operator ! was used
instead of ~ .
