     Pixmaps are offscreen drawables. They can be drawn upon with the
     standard drawing primitives, then copied to another drawable (such
     as a 'GdkWindow') with 'gdkPixmapDraw()'. The depth of a pixmap is
     the number of bits per pixels. Bitmaps are simply pixmaps with a
     depth of 1. (That is, they are monochrome bitmaps - each pixel can
     be either on or off).

     '_G_d_k_P_i_x_m_a_p' An opaque structure representing an offscreen
          drawable. Pointers to structures of type 'GdkPixmap',
          'GdkBitmap', and 'GdkWindow', can often be used
          interchangeably.  The type 'GdkDrawable' refers generically
          to any of these types.


     '_G_d_k_B_i_t_m_a_p' An opaque structure representing an offscreen drawable
          of depth 1. Pointers to structures of type 'GdkPixmap',
          'GdkBitmap', and 'GdkWindow', can often be used
          interchangeably.  The type 'GdkDrawable' refers generically
          to any of these types.

     'gdkPixmap' is the result of collapsing the constructors of
     'GdkPixmap' ('gdkPixmapNew', 'gdkBitmapCreateFromData',
     'gdkPixmapCreateFromData', 'gdkPixmapCreateFromXpm',
     'gdkPixmapColormapCreateFromXpm', 'gdkPixmapCreateFromXpmD',
     'gdkPixmapColormapCreateFromXpmD', NULL, NULL) and accepts a
     subset of its arguments matching the required arguments of one of
     its delegate constructors.
