Is there a way to capture files being dragged onto the application window? I did not find anything related in the docs and it seems as if no special event is generated when doing this. If not, I think this would be a great addition to the library. For mobile applications, the equivalent would probably be share events, where another app shares a files with the gioui app.
Please let me know if this is already supported or possible with some workaround, because I want to build a GUI application precisely around this file drag behaviour.
