     *	Description:  true compile tries to merge all equal points
     *  Note:	      Only input ledges which are copied ( and not linked to ) are taken into account
     *	Note:	      For reasons of speed
     *  Attention:    The current implementation limits the number of points to 65k
     *		      If your resulting ledge contains more points, the engine will crash
     *	Values:	    IVP_SLMP_NO_MERGE	    result needs more memory but compile is fast
     *		    IVP_SLMP_MERGE_AND_REALLOCATE results needs less memory
     *		    IVP_SLMP_MERGE_NO_REALLOCATE result is placed in a chunk of memory
     *				same size as IVP_SLMP_NO_MERGE, but actually needs only
     *				same size as IVP_SLMP_MERGE_AND_REALLOCATE
     *				good for creating intermediate results
