If the text style changes, or the display settings do, we need to update
the state labels to ensure that the glyphs are available in the font
we're using.
Even though the IEC power glyphs are part of Unicode 9.0 (released in
2016) not all fonts have them.
To avoid showing the hexbox of doom when the system font does not have
the glyphs we'd like to use, add a fallback pair, using the old glyphs
we suggested when the labels were translatable.
Unicode 9.0 introduced glyps for the "on" and "off" power states, in the
form of:
- U+23FD POWER ON SYMBOL, or ⏽
- U+2B58 HEAVY CIRCLE, or ⭘
With `HEAVY CIRCLE` as "power off symbol" selected to avoid adding yet
another circle to the standard.
Since we moved GtkSwitch to always show glyphs instead of (translatable)
strings, asking the localisation teams to either come up with a suitable
short string to replace the English "ON" and "OFF", or to fall back to
Unicode glyphs, we should ensure we're using the appropriate symbols to
begin with.

Remove all the old 2.x and 3.x version annotations.
GTK+ 4 is a new start, and from the perspective of a
GTK+ 4 developer all these APIs have been around since
the beginning.
Since setting a clip is mandatory for almost all widgets, we can as well
change the size-allocate signature to include a out_clip parameter, just
like GtkCssGadget did. And since we now always propagate baselines, we
might as well pass that one on to size-allocate.
This way we can also make sure to transform the clip returned from
size-allocate to parent-coordinates, i.e. the same coordinate space
priv->allocation is in.
It's not necessary anymore to receive input events. The pan gesture has
been set on the capture phase as the child widgets may capture during
bubbling.
We now rely on toplevels receiving and forwarding all the events
the windowing should be able to handle. Event masks are no longer a
way to determine whether an event is deliverable ot a widget.
Events will always be delivered in the three captured/target/bubbled
phases, widgets can now just attach GtkEventControllers and let those
handle the events.
Add a new ::measure vfunc similar to GtkCssGadget's that widget
implementations have to override instead of the old get_preferred_width,
get_preferred_height, get_preferred_width_for_height,
get_preferred_height_for_width and
get_preferred_height_and_baseline_for_width.
