Since setting a clip is mandatory for almost all widgets, we can as well change the size-allocate signature to include a out_clip parameter, just like GtkCssGadget did. And since we now always propagate baselines, we might as well pass that one on to size-allocate. This way we can also make sure to transform the clip returned from size-allocate to parent-coordinates, i.e. the same coordinate space priv->allocation is in.

* @Title: GtkSeparator
|
||
*
|
||
* GtkSeparator is a horizontal or vertical separator widget, depending on the
|
||
* value of the #GtkOrientable:orientation property, used to group the widgets
|
||
* within a window. It displays a line with a shadow to make it appear sunken
|
||
* into the interface.
|
||
*
|
||
* # CSS nodes
|
||
*
|
||
* GtkSeparator has a single CSS node with name separator. The node
|
||
* gets one of the .horizontal or .vertical style classes.
