If we set c_marshaller manually, then g_signal_newv() will not setup a
va_marshaller for us. However, if we provide c_marshaller as NULL, it will
setup both the c_marshaller (to g_cclosure_marshal_VOID__VOID) and
va_marshaller (to g_cclosure_marshal_VOID__VOIDv) for us.
When the widget gets finalized it clears the widgetnode and gtk_css_widget_node_get_widget
returns NULL. Guard against gtk_css_widget_node_get_widget() returning NULL like in other
places.

The language is useful for parsing tools, such as that of gtkmm, which
otherwise assumes these are C snippets and elides them from its
generated documentation.
The old GtkBlah node names are just plain obsolete.
This is _gtk_style_context_get_pango_attributes, decoupled
from the GtkStyleContext. This will be used to drive css-styled
text rendering from css subnodes of widgets, e.g. for the value
in GtkScale.
We've changed our API here; what these applications are doing
used to be fine. Don't make users suffer for this by spamming their
logs in a stable release. We'll keep the warning in master.

Always have Since: annotations at the very bottom, use the correct
ClassName::signal-name/ClassName:property-name syntax, fix a few typos
in type names, wrong function names, non-existing type names, etc.
Replace the cursor-color and secondary-cursor-color style
properties with the caret-color and -gtk-secondary-caret-color
CSS properties.
For the 'auto' value of these properties, we keep the same
behavior that we used to have when the style properties are
not explicitly set.
Drop the custom style printing implementation in gtkcssnode.c and
instead reuse the existing gtk_css_style_print function, extending
it a bit to suit our needs.
Instead of computing values, just recognize initial values by
having no CSS section. Also do away with the show-initial flag, and
just always filter out initial values. The flag can come back when
it is needed.
Add a gtk_style_context_to_string function that can serialize
a CSS node or tree of nodes, optionally including CSS properties
as well.
This will be useful in writing tests.
For now, always warn when
gtk_style_context_get()/get_padding()/get_margin()/get_border()
get called with the wrong state.
We used to hide this behind an env var because the warnings were
too frequent, but with the recent refactorings, this warning has become
rather important for detecting bugs.
If it's still problematic, we might want to revert this patch before
3.20.
This new private API, _gtk_style_context_is_background_opaque(), is meant to
be used by internal Gtk+ wigets to optimize fast paths for cases where
applicable. One such use would be to use a CAIRO_CONTENT_COLOR surface
instead of CAIRO_CONTENT_COLOR_ALPHA.

For functions that take state flags as an argument we need to special
case the situation where the passed in flags don't match the current
state.
Previously we would create a copy of the style info, change its state
and do the lookup from there.
Now that GtkCssNode has replaced style infos, this doesn't work as well
anymore as copying a GtkCssNode is not possible.
However, unike style infos, GtkCssNodes are instant-apply, so we don't
need to copy anymore, we can just change the state of the node.
This causes some invalidations to be queued, but we can take that
performance hit as this is fallback code.

We want to clear the style property cache whenever things change in the
tree, not as we previously did only when those changes actually lead to
a different CSS style.
