GtkWidget had a hack where if opacity is 0.999 we set up an opacity group when
rendering the widget. This is no longer needed in 3.10, and GtkStack doesn't
use it anymore.
GdStack is using it, so applications should be ported from GdStack to GtkStack
in 3.12.

Resize modes don't work anymore, both because nobody ever uses them and
because the frame clock changed the way things work quite a bit. So we
don't want to advertise them as a good idea.

Add a has-tab-gap style property to GtkNotebook so that we can
disable drawing the gap between tabs and the page in the Adwaita
theme without breaking existing themes.

GtkSourceView draws before chaining upo to GtkTextView and assumes
that this will be visible, but the pixelcache will just overdraw
that with background.
So, we stop drawing the background to the pixel cache and instead
make it an CAIRO_CONTENT_COLOR_ALPHA surface to make the previously
drawn content see through.
This is slower, but more backwards compatible.

Previously, we were showing and hiding the custom titlebar
widget in response to state changes such as maximization.
Instead, use gtk_widget_set_child_visible() and leave
show/hide to applications. This makes it possible to set
a custom titlebar and hide it, for a titlebar-less appearance.

When loading a symbolic icon, g_file_get_contents() is currently used
with the icon pathname, to load its SVG data. This won't work when the
icon is not a local file, for instance when a symbolic icon is loaded
from a GFileIcon with a GResource path.
Fortunately GtkIconInfo already holds a GFile, so we can just use
g_file_load_contents() to load the data instead.

Updated documentation to specify that '0' should be specified if
one does not need to automatically assign a bound child to a public
or private instance member (now that negative values are private
structure offsets).
If we start with a padding of -1 then it can leak out of the size
allocation request for the column when the treeview is empty. The
GtkTreeView will then collect these -1 values and add them together,
returning -n where 'n' is the number of columns.
This is usually not a problem because treeviews tend to be used with a
scrollbar and the width of the scrollbar will be added to this number
bringing it into positive territory again. On Ubuntu, with overlay
scrollbars, this is not the case, however.
