In gtk_entry_get_icon_pixbuf() we unreference the pixbuf that
_gtk_icon_helper_ensure_pixbuf() gives us back, since the function
doesn't return a reference, and by doing so we're able to return the
reference owned by the cached icon helper.
Since the icon helper method can return NULL though, if no icon
properties have been set on it, guard for != NULL before unreffing the
pixbuf, as that would cause a critical warning.

We can't expose colors with alpha in the GtkStyle colors, since
GdkColor has no alpha. Currently we throw away alpha completely,
which fails very badly for completely transparent backgrounds,
which now is the default for most widgets, as it typically
end up with black-on-black.
We handle this by falling back on the default/previous colors for
transparent colors. This is is simple and avoids complete failure.

(cherry picked from commit 1042372670)
Don't use ASCII control characters to denote the input of Esc, Tab,
Return/Enter, Backspace and Delete, as it seems that it is not how
Windows handle them, and they cause weird characters to appear in the
input field on GTK+3 programs in non-English Windows. Instead, let
these keys be handled as-is on Windows, like what is done in GTK+-2.x.
Checked with mclasen on IRC, and thanks to the people who verified the
patch to not break anything on English Windows.
If the icon view is empty, we cannot get a reasonable size request from
the cell renderers. So all values we would compute are pretty much
useless.
So we special case it.
This also gets rid of a bunch of crashers from div-by-0 in corner cases.

This is useful for 2 reasons:
(1) Items actually exist and are clickable
(2) Size computations don't divide by 0
I've not seen problems with this in the wild (mostly because
item-padding defaults to non-0), but noticed this while fixing other
bugs.
Minimum size is necessary so you can see the item. If we can't get that
we need to scroll.
Natural as the maximum is used so that the spacing between items doesn't
increase when resizing the iconview, but empty space is added to the
right/bottom instead.

While working on the "iconview: Don't shrink items" patch I noticed that
gtk_icon_view_compute_n_items_for_size modifies the natural and minimum
item sizes it got from gtk_icon_view_get_preferred_item_size when
calculating the max number of items which will fit, but later on it
checks against these sizes when calculating the item_size, and these
checks expect these values to be unmodified.
This patch fixes this by modifying the natural and minimum values in
advance and doing all computations with modified values.

The previous code assumed that the width was always enough for more than
one column, which is obviously not correct when a number of columns is
hardcoded.
With this patch, it will now always check that the width is enough and
otherwise cause scrolling.

When I added the versioned annotation, I accidentally backdated
it, so the Deprecated: tag in the docs said 3.4, but the annotation
said 3.0. Fix it so we say 3.4 in both places.
While the docs were adjusted to claim that NULL application-id is allowed,
the code actually segfaulted on it.

GtkPlug directly handles X KeyPress/Release events, instead of using
translation in GDK (which expects XI2 events for XI2). When this
was done, the handling of the group was stubbed out and never replaced.
Export gdk_keymap_x11_group_for_state() and gdk_keymap_x11_is_modifier()
so we can fill out the fields correctly.

This was showing up when using a combo box in list mode. After popping
up the list, the keyboard grab appeared stuck. What was stuck here is
only the client-side grab, since we forgot to clean up our grabs
when receiving an UnmapNotify.
This bug was introduced in 1c97003664.
https://bugzilla.redhat.com//show_bug.cgi?id=812035 has
a stacktrace that shows recursion via
free_node -> unref -> dispose -> ui manager api
which ends in a crash, since we run free_node over the entire
tree and it leaves lots of dangling pointers behind.
So, better be careful by setting all pointers to NULL after
freeing them.
When the toplevel is a GdkOffscreenWindow which doesn't
implement the set_device_cursor() vfunc, we would have
crashed. Implement a dummy ->set_device_cursor vfunc.
