XkbAddGeomOutline(3)			  XKB FUNCTIONS 		     XkbAddGeomOutline(3)

       XkbAddGeomOutline - Add one outline to an existing shape

       XkbOutlinePtr XkbAddGeomOutline ( shape, sz_points )
	     XkbShapePtr shape;
	     int sz_points;

       - shape
	      shape to be updated

       - sz_points
	      number of points to be reserved

       Xkb  provides functions to add a single new element to the top-level keyboard geometry. In
       each case the num_ * fields of the corresponding structure  is  incremented  by	1.  These
       functions  do  not  change  sz_*  unless there is no more room in the array. Some of these
       functions fill in the values of the element's structure	from  the  arguments.  For  other
       functions, you must explicitly write code to fill the structure's elements.

       The  top-level  geometry  description  includes a list of geometry properties.  A geometry
       property associates an arbitrary string with an equally arbitrary name. Programs that dis-
       play  images  of  keyboards  can use geometry properties as hints, but they are not inter-
       preted by Xkb. No other geometry structures refer to geometry properties.

       An outline consists of an arbitrary number of points.  XkbAddGeomOutline adds  an  outline
       to  the specified shape by reserving sz_points points for it. The new outline is allocated
       and zeroed.  XkbAddGeomOutline returns NULL if any of the parameters is empty or if it was
       not  able  to  allocate	space. To allocate space for an arbitrary number of outlines to a
       shape, use XkbAllocGeomOutlines.

	   typedef struct _XkbOutline {
	       unsigned short	 num_points;	  /* number of points in the outline */
	       unsigned short	 sz_points;	  /* size of the points array */
	       unsigned short	 corner_radius;   /* draw corners as circles with this radius */
	       XkbPointPtr	 points;	  /* array of points defining the outline */
	   } XkbOutlineRec, *XkbOutlinePtr;
