The pango code that is drawing hex boxes, invisible glyphs, etc,
is depending on the width being set in the PangoGlyphInfo. Once
we set that, everything falls into place.
Testcase included.
It is a bit annoying that one has to specify the glyph width
when specifying glyphs numerically for a text node, since this
information really is part of the font.
Make the parser more flexible, and allow to specify just the glyph
ids, without an explicit width. In this case, the width will be
determined from the font.
With this, glyphs can now be specified in any of the follwing
ways:
glyphs: "ABC"; (ASCII)
glyphs: 23, 45, 1001; (Glyph IDs)
glyphs: 23 10, 100 11.1; (Glyph IDs and advance widths)
glyphs: 23 10 1 2 color; (with offsets and flags)
Tests have been updated to cover these variants.
While it’s documented as being safe, it triggers warnings from ubsan.
While we work out the best way to deal with that inside the
implementation of `G_ADD_PRIVATE` in GLib, let’s pragmatically just
short-circuit the code which triggers the warning here. This is helpful
because `gdk_display_get_debug_flags()` is called from a number of
locations within GTK, so is likely to be hit if anyone is running a UI
app under ubsan.

Gtk.Editable.get_delegate is allowed to return another
delegating Gtk.Editable. However, the AT-SPI text
implementationn for Gtk.Editables does not handle
delegate chaining.
In the wild, you will find a Gtk.Text as the delegate of
a Gtk.SpinButton, that is in turn the delegate of an
Adw.SpinRow in libadwaita.
Note: This does not handle the more dangerous possibility
of a delegate loop when built with G_DISABLE_ASSERT,
otherwise stops after the arbitrarily chosen number of
six steps of delegation.

When testing VTE on GTK 3 using ATK, the variant parameter is <0> instead
of <''> on the wire. Make that match to increase the chances that tooling
will hit the same expectations.
In an autobuilder environment, there will typically be no hardware GPU
available, so Mesa will fall back from hardware to Zink to software
rendering. Unfortunately, Zink logs to stderr during loading if no
hardware GPUs are available. This particular test asserts that stderr
has desired contents, which means Zink's extra output causes the test
to fail. We can bypass this by disabling use of Zink.

We were installing the timeout in root, but removing it in unmap,
which could lead to trouble if we ever dispose a GtkVideo widget
without mapping it.

The text-mixed-color-nocairo test was using a 20pt font, which
results in 16.6 pixels, which is prone to triggering rounding
errors and problems with fractional node bounds. Make it use
20px instead.
When we've handled a inhibit idle request via Wayland, there is
no need to call into the D-Bus inhibit api unless there's other
inhibit flags to handle.
Fixes: #6470
