extern here is literally C `extern`, not DLL exported functions,

When full-draw is set, use the `rect` passed as argument
to `drawRect` and ignore `drawn_rects` invalidation.
This may fix some missing redraws when switching tabs.
Properly special case first single touch; fall
back to allow windows to emulate mouse events for it.
Yet let gdk handle any multi-touch events, not allowing gestures.
* Fix special case of first single touch. While another touch
is active, any new touch must not get the ID of the (ignored)
first touch.
* reset "last-touch" coordinate on touch-begin.
Previously it was possible that the first motion event was
ignored.
NB: This does not fix missing events when the first touch
coincides with any other finger (gesture?).

Gestures may prevent a 2nd touch from being registered as
such (and instead report a zoom/pinch gesture).
At least that is my best guess, why Nathan needs 3 fingers
to move 2 Faders :)
Popup Dialog Windows never unset the modal flag.
e.g. Session > Save Snapshot & switch.
Furthermore a 2nd dialog was able to get the menu stuck
forever (e.g. Snapshot & Switch .. -> Replace existing?
In order for the Filechooser Location widget to work two
things need to be setup, which only the FileChooserDialog
does:
* subscribe to Widget's "response-requested" signal
* call should_respond () hook from top-level window's
default handler.
The Location Entry emits "activates-default". In case of
the Dialog, that calls the dialogs response callback,
which then calls ` _gtk_file_chooser_embed_should_respond`.
That handles changes made by the user to the location entry.
-=-
Gtk::FileChooserWidget does not handle this, "response-requested"
signal is not exposed, nor is _gtk_file_chooser_embed_should_respond
available outside Gtk.
This change at least selects the file in the treeview, which
allows further handling, without interfering with FileChooserDialog's
behavior.
