We add a separate gtk-a11y.h single-include header for
them. This header will work much the same as gtkx.h. It
will be installed in /usr/include/gtk-3.0/gtk, but you
have to include it separately.
Since we are going to install these headers soon, we need
to make their mutual includes work in the installed location
as well. Also, avoid including individual gtk headers, to
avoid trouble with single-include guards.
This commit exposes the get_type() functions and standard
headers for accessible implementations. This makes it possible
to derive from the GTK accessible implementations without
GType magic tricks. This is necessary, because we require the
a11y type hierarchy to be parallel to the widget type hierarchy.
So, if you derive a widget and need to adjust its a11y implementation,
you have to be able to derive its accessible implementation.
This commit probably exposes more than is absolutely necessary,
it also exposes accessibles of widgets that are unlikely candidates
for deriving from.
Since not every theme renders a background for a GtkViewport (and
Adwaita master doesn't), ensure the grid+viewport we use to emulate a
text view here uses the "view" style class.
It already paints the css border, so let's make it also honor css
background. This is needed to have a box of a different color around
some widgets (e.g. latest gnome-clocks design)
This (shouldn't) change any behaviour, but it moves the
webserver parts to a separate file, making the broadway display file
smaller and preparing for later separating out the server to its own
process.
If you want to get rounded corners on an hbox, instead of
:first-child {
border-top-left-radius: 5px;
border-bottom-left-radius: 5px;
}
:last-child {
border-top-right-radius: 5px;
border-bottom-right-radius: 5px;
}
you now need to write:
:first-child, :last-child:dir(rtl) {
border-top-left-radius: 5px;
border-bottom-left-radius: 5px;
}
:last-child, :first-child:dir(rtl)
{
border-top-right-radius: 5px;
border-bottom-right-radius: 5px;
}

This function is just a sophisitcated optimization.
If we know the GDK window's background will be opaque, we mark it as
opaque. This is so GDK can do all the optimizations it does for opaque
windows and be fast.
This is mainly used when scrolling.
The previous code didn't get this right, in particular it didn't enforce
a transparent background when it knew the background was not opaque.
