Check your header bar styling

[Allan Day <allanpday gmail com>]

Hi all,

As many of you know, we've been making a push to use header bars for
3.10. As a part of this, we have been making a few changes to how
styling works.

Four changes were committed today [1, 2, 3, 4]. These remove as much
hard coded styling from the header bar widget as possible, and specify
the style in the theme instead.

For most applications that are using header bars, there is nothing
that you need to do to compensate for these changes. However, if you
are using the header-bar style from Adwaita and not the header bar
widget, the chances are that you will have to remove any styling that
you have set yourself.

You can see the required adustments on this [5] Nautilus bug.

tl;dr version - if you are using the header-bar css style, please
check your app with gtk+ and gnome-themes-standard master.

Allan
