fltk/FL/Fl.H
Michael R Sweet dc355ebb54 Add Fl::dnd_text_ops() methods.
Fl_Input now conditionally supports DND out via run-time option.

Fl_Input now clears selection if you click inside the selection when
DND is turned on.

Added support for scheme, dndTextOps, and visibleFocus resources under
X11.

Documented all X resources supported under X11...
