/*   Functions used by Xm widgets for the Motif visual drawing   */

/*---------------------------------------------------------------*/

/* All these functions have an Xlib draw like API: 

      a Display*, a Drawable, then GCs, Positions and Dimensions 

      and finally some specific paramaters */

/******** The Draw.c file has been split in several module for

          a better link profile *********/

/*---------------------------------------------------------------

  XmeDrawShadows, 

       use in place of the 1.1 _XmDrawShadow and _XmDrawShadowType

       with changes to the interface (widget vs window, offsets, new order)

       and in the implementation (uses XSegments instead of XRectangles).

       Both etched and regular shadows use now a single private routine

       xmDrawSimpleShadow.

    XmeDrawHighlight.

       Implementation using FillRectangles, for solid highlight only. 

    _XmDrawHighlight.

       Highlight using wide lines, so that dash mode works. 

    XmeClearBorder,    

       new name for _XmEraseShadow  (_XmClearShadowType, which clear half a 

       shadow with a 'widget' API stays in Manager.c ) 

       XmClearBorder is only usable on window, not on drawable.

    XmeDrawSeparator, 

       use in place of the duplicate redisplay method of both separator and 

       separatorgadget (highlight_thickness not used, must be incorporated

       in the function call parameters). use xmDrawSimpleShadow.

       Has 2 new separator types for dash shadowed lines.

    XmeDrawDiamond, 

       new interface for _XmDrawDiamondButton (_XmDrawSquareButton is

       really a simple draw shadow and will be in the widget file as is).

    XmeDrawArrow, 

       same algorithm as before but in one function that re-uses the malloced

       rects and does not store anything in the wigdet instance.

    XmeDrawPolygonShadow,

       new one that use the RegionDrawShadow API to implement an Xme call 

    XmeDrawCircle,

       new one for toggle visual

    XmeDrawIndicator

       new one for toggle drawing
