While the IEC power symbols have been part of Unicode since version 9.0,
released in 2016, not every font supports them.
We can use the old symbols as a fallback, as they seem to have the
better coverage, if not the best appearance.
Instead of from the IMContextQuartz's client window because the former
is the event window where the text will be inserted. In some cases
they're different and the text may be discarded (because the client
window isn't editable) or misplaced.
Fixes Bug 707945.
The cache key is just the name of the cursor, so if a previously added
cursor had e.g. scale == 1, if we ask for a new cursor with scale == 2,
we might still fetch the scale == 1 cursor from the cache. Avoid this by
making sure the scale of the cached one is correct.
If it isn't, load the cursor as normal, and update the cache entry with
the new properly scaled cursor.

When creating the motion controller, we know the widget that is of interest
based on gtk_event_controller_motion_new(). However, not all incoming
events are guaranteed to be of the GdkWindow associated to that widget.
They may also be for a descendant. Therefore, it is useful to translate
those coordinates into the target widget coordinate space as that is
likely what they care about.
CGDisplayModeGetWidth returns 0 if mode is NULL; that happens if the
CGDisplay is offline or mirroring another monitor and it leads to a
divide-by-zero crash.

iter_init_common() is used on uninitialized GtkTextIter, and since neither it
nor its callers initiliaze its padding fields, they contain garbage.
This is a problem for Go - which checks that structs passed to C functions do
not contain pointers to Go-allocated memory - when the garbage happens to be
such a pointer. Although Go zero-fills all GtkTextIter that it allocates, this
does not help when GTK functions such as insert_pixbuf_or_widget_segment called
for gtk_text_buffer_create_child_anchor copy garbage from their stack-allocated
GtkTextIter into a clean iter. To work around this a GtkTextIter has to be
discraded after use in text buffer anchor inserting functions:

So it's able to operate properly with the DnD gesture set by
gtk_drag_source_set(). We usually just react on button release,
that's the right time to claim the gesture.

Signal emittion was added in 6f857f87dc commit and it seems that
this is only place where selected_row is set after emitting signal.
Because of this gtk_list_box_get_selected_row currently returns NULL
as selected row if selection mode is set to GTK_SELECTION_BROWSE.
...since one of the "fixes" there was wrong, at least cosmetically:
.get_position() is declared as returning a gboolean, which is in fact an
int in practice, but we should say what we mean, like we already did.
Make sure that the return types of the vfuncs match the ones that are
specified for post-atk-2.11.x AtkTableCellIface, since we already
require atk-2.15.1 and later.
