+ * @short_description: Graphics in Glk
+ * @include: libchimara/glk.h
+ *
+ * In accordance with this modern age, Glk provides for a modicum of graphical
+ * flair. It does not attempt to be a complete graphical toolkit. Those already
+ * exist. Glk strikes the usual uncomfortable balance between power,
+ * portability, and ease of implementation: commands for arranging pre-supplied
+ * images on the screen and intermixed with text.
+ *
+ * Graphics is an optional capability in Glk; not all libraries support
+ * graphics. This should not be a surprise.
+ *
+ * Most of the graphics commands in Glk deal with image resources. Your program
+ * does not have to worry about how images are stored. Everything is a resource,
+ * and a resource is referred to by an integer identifier. You may, for example,
+ * call a function to display image number 17. The format, loading, and
+ * displaying of that image is entirely up to the Glk library for the platform
+ * in question.
+ *
+ * Of course, it is also desirable to have a platform-independent way to store
+ * sounds and images. Blorb is the official resource-storage format of Glk. A
+ * Glk library does not have to understand Blorb, but it is more likely to
+ * understand Blorb than any other format.
+ *
+ * <note><para>
+ * Glk does not specify the exact format of images, but Blorb does. Images in
+ * a Blorb archive must be PNG or JPEG files. More formats may be added if
+ * real-world experience shows it to be desirable. However, that is in the
+ * domain of the Blorb specification. The Glk spec, and Glk programming, will
+ * not change.
+ * </para></note>
+ *
+ * At present, images can only be drawn in graphics windows and text buffer
+ * windows. In fact, a library may not implement both of these possibilities.
+ * You should test each with the %gestalt_DrawImage selector if you plan to use
+ * it. See <link linkend="chimara-Testing-for-Graphics-Capabilities">Testing for
+ * Graphics Capabilities</link>.

+/**
+ * SECTION:glk-graphics-windows
+ * @short_description: Drawing graphics in graphics windows
+ * @include: libchimara/glk.h
+ *
+ * A graphics window is a rectangular canvas of pixels, upon which you can draw
+ * images. The contents are entirely under your control. You can draw as many
+ * images as you like, at any positions — overlapping if you like. If the
+ * window is resized, you are responsible for redrawing everything. See <link
+ * linkend="wintype-Graphics">Graphics Windows</link>.
+ *
+ * <note><para>
+ * Note that graphics windows do not support a full set of object-drawing
+ * commands, nor can you draw text in them. That may be available in a future
+ * Glk extension. For now, it seems reasonable to limit the task to a single
+ * primitive, the drawing of a raster image. And then there's the ability to
+ * fill a rectangle with a solid color — a small extension, and
+ * hopefully no additional work for the library, since it can already clear
+ * with arbitrary background colors. In fact, if glk_window_fill_rect() did
+ * not exist, an author could invent it — by briefly setting the
+ * background color, erasing a rectangle, and restoring.
+ * </para></note>
+ *
+ * If you call glk_image_draw() or glk_image_draw_scaled() in a graphics window,
+ * @val1 and @val2 are interpreted as X and Y coordinates. The image will be
+ * drawn with its upper left corner at this position.
+ *
+ * It is legitimate for part of the image to fall outside the window; the excess
+ * is not drawn. Note that these are signed arguments, so you can draw an image
+ * which falls outside the left or top edge of the window, as well as the right
+ * or bottom.
+ *
+ * There are a few other commands which apply to graphics windows.
