/**
* GdkPangoRenderer:
*
* #GdkPangoRenderer is a subclass of #PangoRenderer used for rendering
* Pango objects into GDK drawables. The default renderer for a particular
* screen is obtained with gdk_pango_renderer_get_default(); Pango
* functions like pango_renderer_draw_layout() and
* pango_renderer_draw_layout_line() are then used to draw objects with
* the renderer.
*
* In most simple cases, applications can just use gdk_draw_layout(), and
* don't need to directly use #GdkPangoRenderer at all. Using the
* #GdkPangoRenderer directly is most useful when working with a
* transformation such as a rotation, because the Pango drawing functions
* take user space coordinates (coordinates before the transformation)
* instead of device coordinates.
*
* In certain cases it can be useful to subclass #GdkPangoRenderer. Examples
* of reasons to do this are to add handling of custom attributes by
* overriding 'prepare_run' or to do custom drawing of embedded objects
* by overriding 'draw_shape'.
*
* Since: 2.6
