- step back on toning down the borders. Flatness !> legibility.
- darker active state for light
- draw gradinets from bottom up, to keep px sized shading regardless
of button size.
We wrap SVG data from icons within another SVG with extra styling
information. The wrapped SVG may contain characters that cannot be
part of a data: URL (https://fetch.spec.whatwg.org/#data-urls).
Librsvg 2.45 got more strict in its parsing of data: URLs; whereas
previously it ignored '#' characters in them, now it considers them to
be the start of a fragment identifier, which is not allowed in data:
URLs anyway.
To avoid unallowed characters, we now create a data: URL with a
base-64 encoded SVG.

It is permissable to remove a widget using gtk_container_remove from the
gtk_container_foreach callback handler. Document this fact to make it
more discoverable.
Fixes#1461
Gives the same background color to all separators descending from a
title bar than to its direct childrens.
This prevents separators which are in a titlebar but not direct children
from the widget with the titlebar style class from being almost
transparent and hence it prevent them from revealing the clear color of
the window's titlebar (black).

This is better than nothing at all. The wording is taken from Carlos's
commit message when he added this shortly before 3.12, so add Since too.
Skip the bit from his commit message explaining what this replaced; we
don't need to say all the less good things our convenience API replaces.
- Selection mode does not get the special devel styling.
- removed teh last-child() selector for it doesn't work anymore.
Better style all section of the headerbar than none. Proper fix pending.
Commit 1c96b703 changed the way icon
information is given to DnD. Previously an icon helper was kept at
the drag source site. Now an image definition is stored there.
The difference is that icon helper is an object that changes its
state in response to an icon being set, thus the object survived
multiple icon changes. Whereas image definition is destroyed and
re-created from scratch every time a drag icon is changed.
This created a problem where gtk_drag_begin_internal() would receive
the value of site->image_def when a drag just began, then it emits
"drag-begin" signal, in response to which an application can
set drag icon, changing the value of site->image_def. However,
gtk_drag_begin_internal() is unable to know about that change and
continues to use the old value it received from up the stack.
Not only does it prevent drag icon from being set from "drag-begin",
it also can induce a crash, since the old image_def value used
by gtk_drag_begin_internal() points to a freed memory region.
Fix this by only setting a default icon (which is created in-place)
in gtk_drag_begin_internal() if the caller does not care about icons.
Otherwise gtk_drag_begin_internal() will return a boolean that indicates
whether an icon needs to be set. Then the caller can invoke
gtk_drag_set_icon_definition() to set the icon, if needed.
Fixes#1407.
gtk_drag_clear_source_info() immediately unrefs the info attached
to the context (the very same info we're in the process of destroying
in gtk_drag_source_info_free()). If that reference was the last one,
then accessing the info object after that is a use-after-free error.
Also, change the order a bit to first free the event, and only then
unref the context.
Fix this by copying all the fields of the info that we need, and
then working with these copies.
This was noticed in Firefox and demonstrated using a GtkBuilder ui file.
buildable_add_child() calls set_tab_label(), but the latter did nothing
to update the menu_label corresponding to that tab with the new text.
Using Builder to populate the tab child, only tabs other than last got
the right non-default labels, and even that was mostly coincidental, as
adding the main child called update_labels() via real_insert_page(), so
it took effect when the 2nd last main child is added, updating the rest
but leaving the last with the default label, not that given in Builder.
Fix by factoring out the code from child_reordered() to a new helper
menu_item_recreate() and calling that in set_tab_label(), so that
whenever the tab_label is updated, so is its corresponding menu_label.
This fixes the reported case and presumably others that we could write.

The gtk_stack_snapshot_slide() function dereferences the
last_visible_child pointer without proper != NULL ckeck. This might
result in NULL pointer dereference and crash if last_visible_child is
invalid.
Add a != NULL check before dereferencing the pointer.

Before the recent rework of positioning in GtkTooltip, the widget always
used the cursor_size of the GdkDisplay. That work redid this to instead
take GtkSettings::gtk-cursor-theme-size. But that property's doc says:
> Size to use for cursors, or 0 to use the default size.
and has 0 as its default. This is quite a likely scenario for anyone
whose desktop or settings.ini does not explicitly provide a cursor size,
which is the case for XFCE and win32, to name just two common platforms.
Then, it seems getting a cursor_size of 0 causes GtkTooltip to freak out
and hide/show itself at a very rapid speed, thus making it unusable.
So, we should check whether the Settings return 0 and, if so, still use
gdk_display_get_default_cursor_size (display) to ensure we get a size.

gtk_entry_event's goal is to detect if a specific event concerns one of the two
entry icons. It can happen that this function is called during initialization
and/or before the entry is realized. In this case the entry icons (and the
event) will not yet have an associated window. The code should consider the
aforementioned situation and avoid matching a icon and an event with no
associated windows.

All the other conditionally visible child widgets have this. Without it,
it seems some cases can wrongly reveal it, with a nonsensical home icon.

There’s a short-path done for focus rectangles, but it can be taken in other conditions, and then fail occasionally to render a dashed line if the border-width is too big.
