DESCRIPTION
       These procedures provide facilities for drawing window borders in a way
       that  produces a three-dimensional appearance.  Tk_Alloc3DBorderFromObj │
       allocates colors and Pixmaps needed to draw  a  border  in  the	window │
       given  by  the  tkwin  argument.	  The value of objPtr is a standard Tk │
       color name that determines the border colors.  The color	 indicated  by │
       objPtr will not actually be used in the border;	it indicates the back‐ │
       ground color for the window (i.e. a  color  for	flat  surfaces).   The │
       illuminated  portions of the border will appear brighter than indicated │
       by objPtr, and the shadowed portions of the border will	appear	darker │
       than objPtr.							       │

       Tk_Alloc3DBorderFromObj returns a token that may be used in later calls │
       to Tk_Draw3DRectangle.  If an error occurs  in  allocating  information │
       for  the	 border	 (e.g.	a  bogus  color	 name  was given) then NULL is │
       returned and an error message is left in interp->result.	 If it returns │
       successfully,  Tk_Alloc3DBorderFromObj  caches  information  about  the │
       return value in objPtr, which speeds up future calls to	Tk_Alloc3DBor‐ │
       derFromObj with the same objPtr and tkwin.			       │

       Tk_Get3DBorder  is identical to Tk_Alloc3DBorderFromObj except that the │
       color is specified with a string instead of an object.	This  prevents │
       Tk_Get3DBorder from caching the return value, so Tk_Get3DBorder is less │
       efficient than Tk_Alloc3DBorderFromObj.				       │

       Tk_Get3DBorderFromObj returns the token for an existing	border,	 given │
       the  window  and color name used to create the border.  Tk_Get3DBorder‐ │
       FromObj doesn't actually create the border; it must already  have  been │
       created with a previous call to Tk_Alloc3DBorderFromObj or Tk_Get3DBor‐ │
       der.  The return value is cached in  objPtr,  which  speeds  up	future │
       calls to Tk_Get3DBorderFromObj with the same objPtr and tkwin.

       Once  a	border	structure  has been created, Tk_Draw3DRectangle may be
       invoked to draw the border.  The tkwin argument	specifies  the	window
       for  which the border was allocated, and drawable specifies a window or
       pixmap in which the border is to be drawn.  Drawable need not refer  to
       the  same  window as tkwin, but it must refer to a compatible pixmap or
       window:	one associated with the same screen and with the same depth as
       tkwin.	The  x, y, width, and height arguments define the bounding box
       of the border region within drawable (usually x	and  y	are  zero  and
       width  and  height  are	the dimensions of the window), and borderWidth
       specifies the number of pixels actually occupied by  the	 border.   The
       relief argument indicates which of several three-dimensional effects is
       desired: TK_RELIEF_RAISED means that  the  interior  of	the  rectangle
       should  appear  raised  relative	 to the exterior of the rectangle, and
       TK_RELIEF_SUNKEN means  that  the  interior  should  appear  depressed.
       TK_RELIEF_GROOVE	 and  TK_RELIEF_RIDGE mean that there should appear to
       be a groove or ridge around the exterior of the rectangle.

       Tk_Fill3DRectangle is somewhat like Tk_Draw3DRectangle except  that  it
       first  fills the rectangular area with the background color (one corre‐
       sponding	 to  the  color	 used  to  create  border).   Then  it	 calls
       Tk_Draw3DRectangle  to  draw a border just inside the outer edge of the
       rectangular area.  The argument relief  indicates  the  desired	effect
       (TK_RELIEF_FLAT means no border should be drawn; all that happens is to
       fill the rectangle with the background color).

       The procedure Tk_Draw3DPolygon may be used to draw more complex	shapes
       with  a three-dimensional appearance.  The pointPtr and numPoints argu‐
       ments define a trajectory, polyBorderWidth indicates how wide the  bor‐
       der  should  be	(and  on which side of the trajectory to draw it), and
       leftRelief indicates which side of the trajectory should appear raised.
       Tk_Draw3DPolygon	 draws	a border around the given trajectory using the
       colors from border to produce a three-dimensional appearance.   If  the
       trajectory is non-self-intersecting, the appearance will be a raised or
       sunken  polygon	shape.	 The  trajectory  may  be   self-intersecting,
       although it's not clear how useful this is.

       Tk_Fill3DPolygon	 is  to Tk_Draw3DPolygon what Tk_Fill3DRectangle is to
       Tk_Draw3DRectangle:  it fills the polygonal area	 with  the  background
       color  from border, then calls Tk_Draw3DPolygon to draw a border around
       the area (unless leftRelief is TK_RELIEF_FLAT;  in this case no	border
       is drawn).

       The  procedures	Tk_3DVerticalBevel  and	 Tk_3DHorizontalBevel  provide
       lower-level drawing primitives that are	used  by  procedures  such  as
       Tk_Draw3DRectangle.   These  procedures	are  also  useful in their own
       right for drawing rectilinear border shapes.  Tk_3DVerticalBevel	 draws
       a vertical beveled edge, such as the left or right side of a rectangle,
       and Tk_3DHorizontalBevel draws a horizontal beveled edge, such  as  the
       top  or	bottom	of a rectangle.	 Each procedure takes x, y, width, and
       height arguments that describe the rectangular area of the beveled edge
       (e.g., width is the border width for Tk_3DVerticalBevel).  The leftBor‐
       der and topBorder arguments indicate the position of the	 border	 rela‐
       tive  to	 the ``inside'' of the object, and relief indicates the relief
       of the inside of the object relative to	the  outside.	Tk_3DVertical‐
       Bevel  just  draws  a rectangular region.  Tk_3DHorizontalBevel draws a
       trapezoidal region to generate mitered corners;	it  should  be	called
       after  Tk_3DVerticalBevel  (otherwise Tk_3DVerticalBevel will overwrite
       the mitering in the corner).   The  leftIn  and	rightIn	 arguments  to
       Tk_3DHorizontalBevel  describe the mitering at the corners;  a value of
       1 means that the bottom edge of the trapezoid will be shorter than  the
       top,  0	means  it  will be longer.  For example, to draw a rectangular
       border the top bevel should  be	drawn  with  1	for  both  leftIn  and
       rightIn,	 and  the  bottom  bevel should be drawn with 0 for both argu‐
       ments.

       The procedure Tk_SetBackgroundFromBorder	 will  modify  the  background
       pixel  and/or  pixmap of tkwin to produce a result compatible with bor‐
       der.  For color displays, the resulting background  will	 just  be  the
       color  specified when border was created;  for monochrome displays, the
       resulting background will be a light stipple pattern, in order to  dis‐
       tinguish the background from the illuminated portion of the border.

       Given a token for a border, the procedure Tk_NameOf3DBorder will return
       the color name that was used to create the border.

       The procedure Tk_3DBorderColor returns the XColor structure  that  will
       be  used	 for flat surfaces drawn for its border argument by procedures
       like Tk_Fill3DRectangle.	 The return value  corresponds	to  the	 color
       name  that  was used to create the border.  The XColor, and its associ‐
       ated pixel value, will remain allocated as long as border exists.

       The procedure Tk_3DBorderGC returns one of the X graphics contexts that
       are  used  to draw the border.  The argument which selects which one of
       the three possible GC's: TK_3D_FLAT_GC returns  the  context  used  for
       flat  surfaces,	TK_3D_LIGHT_GC	returns the context for light shadows,
       and TK_3D_DARK_GC returns the context for dark shadows.

       When  a	border	is  no	longer	 needed,   Tk_Free3DBorderFromObj   or │
       Tk_Free3DBorder	should	be  called to release the resources associated │
       with it.	 For Tk_Free3DBorderFromObj the border to release is specified │
       with  the  window  and  color  name  used  to  create  the  border; for │
       Tk_Free3DBorder the border to release is specified with the Tk_3DBorder │
       token   for   the   border.   There  should  be	exactly	 one  call  to │
       Tk_Free3DBorderFromObj	or   Tk_Free3DBorder   for   each   call    to │
       Tk_Alloc3DBorderFromObj or Tk_Get3DBorder.
