+/**
+ * @defgroup xcb__image_t XCB Image Functions
+ * 
+ * These are functions used to create and manipulate X images.
+ * 
+ * The X image format we use is specific to this software,
+ * which is probably a bug; it represents an intermediate
+ * position between the wire format used by the X GetImage
+ * and PutImage requests and standard formats like PBM.  An
+ * image consists of a header of type @ref xcb_image_t
+ * describing the properties of the image, together with a
+ * pointer to the image data itself.
+ * 
+ * X wire images come in three formats.  An xy-bitmap is a
+ * bit-packed format that will be expanded to a two-color
+ * pixmap using a GC when sent over the wire by PutImage.
+ * An xy-pixmap is one or more bit-planes, each in the same
+ * format as xy-bitmap.  A z-pixmap is a more conventional
+ * pixmap representation, with each pixel packed into a
+ * word.  Pixmaps are sent and received over the wire only
+ * to/from drawables of their depth.
+ * 
+ * Each X server defines, for each depth and format,
+ * properties of images in that format that are sent and
+ * received on the wire.  We refer to this as a "native"
+ * image for a given X server.  It is not uncommon to want
+ * to work with non-native images on the client side, or to
+ * convert between the native images of different servers.
+ *
+ * This library provides several things.  Facilities for
+ * creating and destroying images are, of course, provided.
+ * Wrappers for xcb_get_image() and xcb_put_image() are
+ * provided; these utilize the image header to simplify the
+ * interface.  Routines for getting and putting image pixels
+ * are provided: both a generic form that works with
+ * arbitrary images, and fastpath forms for some common
+ * cases.  Conversion routines are provided for X images;
+ * these routines have been fairly well optimized for the
+ * common cases, and should run fast even on older hardware.
+ * A routine analogous to Xlib's XCreate*FromBitmapData() is
+ * provided for creating X images from xbm-format data; this
+ * routine is in this library only because it is a trivial
+ * use case for the library.

+ * XCB Image fast pixel ops.
+ *
+ * Fast inline versions of xcb_image_get_pixel() and
+ * xcb_image_put_pixel() for various common cases.
+ * The naming convention is xcb_image_put_pixel_FUB()
+ * where F is the format and is either XY for bitmaps
+ * or Z for pixmaps, U is the bitmap unit size or pixmap
+ * bits-per-pixel, and B is the endianness (if needed)
+ * and is either M for most-significant-first or L for
+ * least-significant-first.  Note that no checking
+ * is done on the arguments to these routines---caller beware.
+ * Also note that the pixel type is chosen to be appropriate
+ * to the unit; bitmaps use int and pixmaps use the appropriate
+ * size of unsigned.
