`gtk_builder_get_parameters()` is a hot path, being called twice for
each object in each UI file in an application. The majority of objects
have ≤ 8 properties, which are each filtered into either `parameters` or
`filtered_parameters`.
Unfortunately, both of those arrays are created as empty `GArray`s, and
adding 8 elements to an empty `GArray` hits the worst possible case of
reallocating and `memcpy()`ing the array 3 times. As the array size is
doubled with each reallocation, the cost is not particularly well
amortised when the array size is small.
From the `ObjectInfo`, we actually know how many properties there are in
total, so just allocate the arrays at the right size to begin with.
This saves 7% of the instruction cycles needed to start up
gnome-software to the point where it’s showing its main window,
according to callgrind. gnome-software is making around 5500 calls to
`gtk_builder_get_parameters()`.

The included fribidi header is not used in gdkkeys-wayland.c and already
included in gdk.c which causes linker issues due to the header defining
a global variable.
Before I tried this change, I thought it might break apps that do
transparent window background. So I checked a few that did this:
gnome-terminal, tilix, kgx. It worked, so it must work everywhere, right?
However, it just so happens that vte is drawn using CAIRO_OPERATOR_SOURCE
operator rather than CAIRO_OPERATOR_OVER like everything else. This means
that if vte widget is transparent, anything below it, like a black
decoration background, won't be shown.
So really it is still broken, so reverting it.
Trash monitor queries info from gvfsd-trash after each file monitor
change which can be problematic when too many changes happen in
a short time. Let's rate limit the number of queries...
Fixes: #1010
- Remove various unnecessary overrides for linked buttons.
- Add missing outline styles to the %linked_vertical ones.
- Consistently use :not(.vertical) instead of :dir(ltr|rtl) for linked
combo buttons.
- Remove :only-child styling from the messagedialog button. The
:only-child is equivalent to :first-child:last-child, so we don't need
the styling there specially.

Provide the minimal info necessary. Improves apparent responsiveness
(since we don't visibly clear and repopulate the list) and saves doing
file stat/reads on every file in the result set.
The filechooser tries to figure out whether it got results by poking
the model, but all files might go through the async GFileInfo querying
state.
Make all search engines (and the composite one) just notify about this
fact, so the file chooser can behave appropriately without waiting for
the async operations to finish.
The tablet device is the source device of the event. We must use
the source device to properly detect what kind of source we must
use to properly set the color.
If the tablet gets removed/freed while there are pad events in flight,
we leave a dangling pointer from the pad to the tablet, which may
lead to invalid reads/writes when handling the pad event(s).

Once upon a time, there was a function called gdk_event_get_scroll_deltas().
It returned %TRUE when an event had scroll deltas and that was used as the
condition to decide whether to push scroll deltas to the scroll history,
even when the both deltas are 0 for the stop event at the end of scrolling.
When GtkScrolledWindow kinetic scrolling code was adapted for
GtkEventControllerScroll, it was replaced with a (dx != 0 && dy != 0)
check. This prevented the stop event from getting into the history, and
instead allowed non-smooth scrolling to affect the history as they have
synthetic deltas with one of the values being -1 or 1 and the other on 0.
Instead, check the direction as we already have it as a local variable.
To avoid making this mistake again, add a static assertion that the
enum is in sync with gtk_license_info, and use the length of
gtk_license_info for the precondition check.

Resolves: #2734
Reading form the back buffer is not allowed on software renderers,
and this is reported by the buffer age, so reading from GL_BACK
should not be done when the age is 0
