combo_box_popdown() of course doesn’t popdown our menu if it is NULL.
But the required call to this at end-of-life was in destroy(), by which
point dispose() already NULLed the menu, so Menu::popdown() would never
run, even if it should. Fix this by trying popdown() earlier in unmap().
Also, add a converse assurance that we don’t popup() while not mapped.
The documents state that gtk_scale_set_digits() “causes the value of the
adjustment to be rounded off to this number of digits, so the retrieved
value matches the value the user saw.” Note the lack of any condition.
But in fact, if draw-value was false, rounding was disabled on the base
Range, so values that weren’t displayed weren’t rounded. This made the
docs wrong and made an apparently cosmetic detail alter functionality.
Fix by ensuring the number of digits set on Scale is always propagated
along to gtk_range_set_round_digits(), thus rounding to it in all cases
when the value changes, regardless of whether the value is displayed.
This doesn’t address the other idea from Bugzilla: that changing the
number of digits should clamp the _existing_ value if it’s more precise.
This contradicts digits docs in the base Range, but the above from Scale
can be read as implying it’ll happen. For now, that’s an open question.

Also, "ie" wasn't very clear, but fixing that to "i.e." would cause
truncation of the summary when processed by bindings using doxygen. So,
I replaced it with "in other words", which is no _less_ clear, at least.
...which treats the first '.' in doc comments as the end of the summary.
So, e.g., in gtkmm, get_kinetic_scrolling() is currently summarised as
"Changes the behaviour of @scrolled_window wrt." Not very informative!
No need for a period there & anyway, the phrase "wrt to" is superfluous,
and we have space to actually say "with regard to", so just do that now.
drag-data-delete is emitted based on the interchange of the
DELETE atom, which may well be set or bypassed locally by
the app. As such emitting it here is not right, the other
paths handling the DELETE atom interchange are still valid
and there.

to hilight drop target there is a wildcard selector which turns
the border and shadow to green, this clearly shouldn't happen when
the whole window is a drop target.
The code always assumed that getting a row at a certain 'y' was
possible but if the list box has more empty space than rows then a
valid row may not be retrieved.

We were using __VOID for the SHOW_OTHER_LOCATION signal that
uses flags named SHOR_OTHER_LOCATION_WITH_FLAGS.
However, if a signal uses flags the marshal needs to use __FLAGS.
This patch addresses this using VOID__FLAGS as the marshaler parameter.
Thanks to Jan Steffens for pointing this out.
