/**
* SECTION:hdy-window
* @short_description: A freeform window.
* @title: HdyWindow
* @See_also: #HdyApplicationWindow, #HdyHeaderBar, #HdyWindowHandle
*
* The HdyWindow widget is a subclass of #GtkWindow which has no titlebar area
* and provides rounded corners on all sides, ensuring they can never be
* overlapped by the content. This makes it safe to use headerbars in the
* content area as follows:
*
* |[
* <object class="HdyWindow"/>
* <child>
* <object class="GtkBox">
* <property name="visible">True</property>
* <property name="orientation">vertical</property>
* <child>
* <object class="HdyHeaderBar">
* <property name="visible">True</property>
* <property name="show-close-button">True</property>
* </object>
* </child>
* <child>
* ...
* </child>
* </object>
* </child>
* </object>
* ]|
*
* It's recommended to use #HdyHeaderBar with #HdyWindow, as unlike
* #GtkHeaderBar it remains draggable inside the window. Otherwise,
* #HdyWindowHandle can be used.
*
* #HdyWindow allows to easily implement titlebar autohiding by putting the
* headerbar inside a #GtkRevealer, and to show titlebar above content by
* putting it into a #GtkOverlay instead of #GtkBox.
*
* if the window has a #GtkGLArea, it may bring a slight performance regression
* when the window is not fullscreen, tiled or maximized.
*
* Using gtk_window_get_titlebar() and gtk_window_set_titlebar() is not
* supported and will result in a crash.
*
* # CSS nodes
*
* #HdyWindow has a main CSS node with the name window and style classes
* .background, .csd and .unified.
*
* The .solid-csd style class on the main node is used for client-side
* decorations without invisible borders.
*
* #HdyWindow also represents window states with the following
* style classes on the main node: .tiled, .maximized, .fullscreen.
*
* It contains the subnodes decoration for window shadow and/or border,
* decoration-overlay for the sheen on top of the window, widget.titlebar, and
* deck, which contains the child inside the window.
*
* Since: 1.0
