I'd prefer this being an event of TApplication. Possibly with a
reference to the form/component the files were dropped on, if any.
Maybe implement it in TApplication and TForm, so one can intercept and
handle the message at App level or have it automatically delegated to
either the current active form (OS X dbl-click) or the form on which
the files were dropped (win / x drag'n'drop).
