Michael Natterer 791ac426d7 define __GDK_H_INSIDE__ around including all other headers.
2008-05-28  Michael Natterer  <mitch@imendio.com>

	* gdk/gdk.h: define __GDK_H_INSIDE__ around including all other
	headers.

	* gdk/gdkenumtypes.h.template
	* gdk/gdk*.h: add single-include guards that #error out if
	GTK_DISABLE_SINGLE_INCLUDES is defined and any of these files is
	included individually. Also removed some redundant includes and
	did some tiny trailing whitespace removal that's not worth to
	commit separately.

	* gdk/gdkprivate.h: include <gdk/gdk.h> instead of individual
	files.

	* gdk/win32/gdkwin32.h
	* gdk/x11/gdkx.h: only include <gdk/gdkprivate.h> and remove all
	other includes.

/**
* 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
