The root path is shared by all AtSpiContext instances, so we should
compute it once, instead of every time we instantiate a new context.
This allows us to defer the path creation at realization time and ensure
that we have a registered application.
The expected behavior when activating check or radio
menuitems via keynav is that Space toggles the item
but keeps the menu open, while Return toggles the
item and closes the menu.
Ever since 5b5d2665d3, tooltips don't work properly,
since we get more motion events now, and those keep the
tooltips from appearing. This can be seen e.g. on the icon
in the password entry in widget-factory, or on the section
switcher buttons in the Emoji chooser.
Ignore synthetic motion events for the purposes of
determining whether the user moved the mouse.
Currently GTK can be built with G_ENABLE_DEBUG which enables various debug code and parsing
of those env vars, or without, which instead of parsing them prints a warning if they are set.
While building with G_ENABLE_DEBUG isn't strictly needed it's the only way to make GTK_DEBUG=interactive work,
which is a nice thing to have always.
This enables parsing of those env vars in any case and allows specific values being marked as also
available when not built with G_ENABLE_DEBUG (interactive for example). If not built with G_ENABLE_DEBUG
then all unavailable values will be marked as such in the help output and a note is added that
GTK needs to be built with G_ENABLE_DEBUG to use them, which should help discoverability.
An implicit grab means some button is down, reset the active state
only in that case when we get a grab broken event.
Avoids active state accounting warnings when we do get active grabs
broken (e.g. after selecting a menu option).
Since the $button_fill variables are no longer used outside of the
button() mixin (and it was for an ugly hack), there is no need to keep
that anymore.

We may have the situation of multiple touchpoints in the same
widget, or combinations with other devices. Stack those ::active
states are preserved on widgets on all but the last pointer/touch
going away.
Use the GROUP role, and make sure to note that the child is always
revealed. Unlike GtkExpander, GtkRevealer can only be programmatically
toggled, so we cannot turn it into a "button" object.
Document the role of the GtkTreeExpander, and the behaviour of the
expander button.
Additionally, improve the label of the expander button, by adding a
fixed "Expand" label, and setting the "labelled-by" relation to the
child of the GtkTreeExpander.
The search bar widget has a "SEARCH" landmark role, which is described
as:
A landmark region that contains a collection of items and
objects that, as a whole, combine to create a search facility.
