Being addable to a ScrolledWindow is not interesting; now that SW
auto-adds a Viewport if needed, so can DrawingArea and any other widget.
Mention GtkFixed in case the reader just wants that bit of functionality
This adds support for the shortcut inhibitor protocol in gdk/wayland
backend.
A shortcut inhibitor request is issued from the gdk wayland backend for
both the older, deprecated API gdk_device_grab() and the new gdk seat
API gdk_seat_grab(), but only if the requested capability is for the
keyboard only.

If query.return_type is not one we want, binding_compose_params() is
not called, and so params remains a NULL pointer. However, the code was
then unconditionally iterating it regardless. Don't if it is still NULL.
CID 1452218 (#1 of 1): Explicit null dereferenced (FORWARD_NULL)
15. var_deref_op: Dereferencing null pointer params.
This would only happen if the last element was deprecated, but it should
be avoided anyway.
CID 1388852 (#1 of 1): Out-of-bounds read (OVERRUN)
12. overrun-local: Overrunning array pseudo_classes of 16 32-byte
elements at element index 16 (byte offset 512) using index i + 1U (which
evaluates to 16).
This function clearly assumes the parameter children cannot be NULL, and
the call sites seem to perform enough checks to confirm this.
CID 1388869 (#1 of 1): Dereference before null check (REVERSE_INULL)
check_after_deref: Null-checking children suggests that it may be null,
but it has already been dereferenced on all paths leading to the check.
CID 1432024 (#1 of 1): Uninitialized scalar variable (UNINIT)
2. uninit_use_in_call: Using uninitialized value rect.x when calling
calendar_arrow_rectangle.
Add a default case to the switch which will bail out with
g_assert_not_reached(), which should reassure Coverity that the method
is always called with a valid value that is handled in the switch.
If value->values[i] is NULL, then values[i] was left uninitialised.
The code then reads each element of values[].
CID 1432029 (#1 of 1): Uninitialized pointer read (UNINIT)
11. uninit_use: Using uninitialized value values[i].
Our ::query-tooltip handler first checks whether the pointer is over any
of the icons, returning their tooltip if so, and if not chains up to
Widget::query-tooltip in order to show the text for the widget overall.
But ensure_has_tooltip(), which exists to update :has-tooltip based on
whether ::query-tooltip is needed, only set :has-tooltip to TRUE if any
icon had a tooltip, without caring whether the widget as a whole does.
That is asymmetrical and meant that if the Entry had a tooltip, but
subsequently all icons had their tooltips unset, :has-tooltip would be
set to FALSE, and hence the tooltip for the widget would become lost.
The fix is to set :has-tooltip to TRUE if the widget has a tooltip of
its own, and we only need to check the icons if that is not the case.

This was comparing the input position, which is documented as being
relative to the top-left of the Entry allocation, to icon allocations
that were not adjusted accordingly. This could result in tooltips for
icons not being shown in various conditions, since the ::query-tooltip
handler uses get_icon_at_pos() to check whether to show an icon tooltip.
The fix is to compare to the icon border box, not border allocation, as
CssGadget::get_border_box() adjusts relative to the widget. Better yet:
we can just make CssGadget::border_box_contains_point() compare for us.
Delegating to Entry::get_icon_area(), which manually reimplements
CssGadget::get_border_box(), would also work, but this is simpler.

Just to test tooltips in all cases; what was already here
should have been sufficient, but this doesn't hurt.
While here, also add some instructive placeholder text.

We can e.g. get the entry dispose()d and a focus_out event after that
(because the toplevel unsets the focus which previously was the entry).
We then later use priv->current_pos in a call to pango API which makes
sure the given index is valid for the given layout. Since we lazily
create a GtkEntryBuffer in get_buffer() and a PangoLayout lazily in
gtk_entry_create_layout, these 2 are always valid but don't match
priv->current_pos in this situation.
Fix this by resetting priv->current-pos in dispose().

There's GDK grab situations (eg. pointer motion outside the grab window
in combination with a GTK+ grab) where a gesture may receive events from
windows that are not the widget's.
The _update_widget_coordinates() still does work for those situations, so
just let these events go through instead of ignoring them.
https://bugzilla.gnome.org/show_bug.cgi?id=782870
Refactor the code updating the active link under the current coordinates
into a separate function, and call it on GtkGestureMultiPress::pressed
so the link is updated on GDK_TOUCH_BEGIN. Based on a patch by
Jan-Michael Brummer <jan.brummer@tabos.org>.

Setting the cursor on the widget window (i.e. the parent widget's) is
finicky because the cursor needs to be updated on crossing events, and
will yield the wrong result for other master devices that happen to be
in other areas of the same parent widget's window.
Just set it always on the event window created by the GtkButton parent
class. That window was causing the crossing events, so the rectangle
that gets the hand cursor set will be the same size, and we don't need
to track pointer crossing state that way.

This check must be done explicitly on Wayland as the master device for
tablet tools differ from the Core Pointer. This ensures that whenever a
tablet tool is inside a window and the cursor is programmatically changed,
it will be visually updated too.
https://bugzilla.gnome.org/show_bug.cgi?id=785375
Adds support for creating scroll events from Wayland tablet wheel events.
Even though no Wacom tablet puck has a smooth-scrolling wheel, both event
types need to be generated to make the upper layers happy.

If a tablet device is used to perform actions like window moving or resizing,
GTK must provide the correct implicit grab serial number over Wayland to Mutter
in order for the action to succeed. This commit adds tablet support to the
implicit serial getters.

If a bad behaving application tries to make the window/display beep too
often, throttle the beep requests so that we don't end up filling the
Wayland socket queue.
The throttle is set to 50 beeps per second, which far more beeps than
will ever make any sense from a user experience point of view, but will
avoid terminating due to an excessive amount of requests.
