For some of the a11y states, calling gtk_accessible_reset_state
can change the type of the state value from boolean or tristate
to undefined.
Handle that, instead of throwing criticals.

The code in the fontrendering demo is a bit sloppy
and assumes that we always get a single run when
appending a sequence of 4 chars and 4 spaces.
That is not in general true, such as for Emoji.
Instead of working harder to handle Emoji here,
just give up and fall back to 'a'.

We need to register the portal mime types before
the others to prefer them, doing this call async
messes up that ordering.

When the IM commands the GtkText to delete text, the cursor position
would change, and so would the surrounding text. Reset the IM context
so that these updates are properly picked up by the IM.
Fixes backspace key behavior in the GNOME Shell OSK, since that relies
on the surrounding text being properly updated for the next iteration.

Resetting the IM on IM updates is too eager and indeed the simple
IM context doesn't like that this happens in the middle of dead
key handling.
We however want to reset the IM after actual text buffer changes
(say, a committed string) moved the cursor position, altered the
surrounding text, etc. So that the IM implementation does know to
update its state.
Since there is going to be an actual IM reset anyways, it does
no longer make sense to try to preserve the old priv->need_im_reset
status during commit handling.

Update the label size request when setting the digits property
by calling the update_label_request () util function.
That util function works by measuring the size request of the
label with the lower and upper values of the adjustment, then
taking the max. That way the size requisition is constant
regardless of the actual displayed value.
Since the util function internally works by setting the text
of the label, let it also set the text at last by taking in
account the current adjustment's value. Most of its callers
do that anyway.

If you've begun a user action and call `gtk_text_buffer_set_text`, you
get an unexpected warning:
```
Gtk-WARNING **: Cannot begin irreversible action while in user action
```
which can be fixed by doing the delete/insert yourself. But this is not
documented as occurring, so document it.
`apply_monitor_change()` already calls `update_scale()`.
Note that this only affects old compositor versions (see
`should_update_monitor()`) so it's just a minor cleanup.
