Don't install headers for code that we don't build.
And don't include those headers in gsk.h.
Just as we do in gdk, require applications to include
the backend-specific headers they need explicitly.
Update the one affected demo, gtk4-node-editor.
We are comparing a transparent label to a transparent
text view, so need to make sure the caret does not show
up in the text view to ruin the comparison.
Some machinery (like clicking on expander) relies on prelight state
being up to date, but we don't set prelight on touch events. Do that
transiently, as long as a row is clicked.
Fixes tapping on expanders.
If the wl_surface receiving touch events is destroyed, we will get no
wl_touch.up event to remove the touchpoint from our internal accounting.
Check for this, and drop touchpoints happening in surfaces that do
disappear during operation.
If the popover fails to be shown, it would internally undo visible
and mapped state. If we just proceed as normal, the widget enters
in inconsistent state, and a grab remains issued on the invisible
widget, preventing further input from the input device.
This function to revoke implicit grabs may be called with a NULL
device, which means all devices should be revoked. Fix the check
so this actually happens.
Fixes implicit grabs (maybe) being unset in result to a GTK grab.
Update the layout when any of the following properties changes:
* modal
* transient-for
* resizable
* deletable
Stop updating it from GtkWindow, make that function static.
Only turn on visible focus when a key event actually leads
to a change in focus location (ie, 'keynav').
Make the visible focus disappear after 5 seconds of no
keyboard interaction, to avoid permanent focus ring
distraction.
As an extra bonus, make it so that we make the focus
visible while the Alt key is pressed. This gives us
a 'find my focus!' shortcut, and goes well with the
prexisting use of Alt for finding mnemonics.

In the n == 2 case, we want to avoid the buttons being
drawn all the way out to the ends of the box, but in the
n >= 3 case, that is exactly what we want for the first
and last button.
When the icon theme changes, we want to both initiate
a css SOURCE change (since css values may depend on the
icon theme), as well as calling gtk_system_setting_changed,
since widgets need to drop cached images, e.g. in GtkIconHelper.
Replace calls to gtk_style_context_reset_widgets by
gtk_system_setting_changed, with the appropriate setting,
and add style invalidation where required.
This gives us a hook to walk the widget tree whenever a global
setting changes and do per-widget invalidations. This will
replace gtk_style_context_reset_widgets().
