* Selectors work very similar to the way they do in CSS, with widget class
* names taking the role of element names, and widget names taking the role
* of IDs. When used in a selector, widget names must be prefixed with a
* '&num;' character. The '*' character represents the so-called universal
* selector, which matches any widget.
* </para>
* <para>
* To express more complicated situations, selectors can be combined in
* various ways:
* <itemizedlist>
* <listitem><para>To require that a widget satisfies several conditions,
* combine several selectors into one by concatenating them. E.g.
* <literal>GtkButton&num;button1</literal> matches a GtkButton widget
* with the name button1.</para></listitem>
* <listitem><para>To only match a widget when it occurs inside some other
* widget, write the two selectors after each other, separated by whitespace.
* E.g. <literal>GtkToolBar GtkButton</literal> matches GtkButton widgets
* that occur inside a GtkToolBar.</para></listitem>
* <listitem><para>In the previous example, the GtkButton is matched even
* if it occurs deeply nested inside the toolbar. To restrict the match
* to direct children of the parent widget, insert a '>' character between
* the two selectors. E.g. <literal>GtkNotebook > GtkLabel</literal> matches
* GtkLabel widgets that are direct children of a GtkNotebook.</para></listitem>

* GtkThemingEngines can register their own, engine-specific style properties
* with the function gtk_theming_engine_register_property(). These properties
* can be set in CSS like other properties, using a name of the form
* <literallayout>-<replaceable>namespace</replaceable>-<replaceable>name</replaceable></literallayout>, where <replaceable>namespace</replaceable> is typically
* the name of the theming engine, and <replaceable>name</replaceable> is the
* name of the property. Style properties that have been registered by widgets
* using gtk_widget_class_install_style_property() can also be set in this
* way, using the widget class name for <replaceable>namespace</replaceable>.

Make invalid stylesheets fail to parse again The recent improvements to error reporting caused gtk_css_provider_load... to always return TRUE and leave the error unset. Error messages were instead dumped out with g_message, which is not helpful. This commit changes things back to the way they were before: If a GError is passed in, parsing will fail at the first error, reporting it in the given GError. If no GError is passed in, we keep going and just issue the warning messages. This fixes the parser tests.

Make invalid stylesheets fail to parse again The recent improvements to error reporting caused gtk_css_provider_load... to always return TRUE and leave the error unset. Error messages were instead dumped out with g_message, which is not helpful. This commit changes things back to the way they were before: If a GError is passed in, parsing will fail at the first error, reporting it in the given GError. If no GError is passed in, we keep going and just issue the warning messages. This fixes the parser tests.

Make invalid stylesheets fail to parse again The recent improvements to error reporting caused gtk_css_provider_load... to always return TRUE and leave the error unset. Error messages were instead dumped out with g_message, which is not helpful. This commit changes things back to the way they were before: If a GError is passed in, parsing will fail at the first error, reporting it in the given GError. If no GError is passed in, we keep going and just issue the warning messages. This fixes the parser tests.
