int UPRJ_def__	(	int	typ,
		void *	target,
		Vector *	vc1
	)

    init projection with target & projectionDirection
    INPUT:
      typ     typ of projectionTarget; must be Typ_PLN
      target  typ=Typ_PLN: (Plane*)
              typ=Typ_SURMSH: (int*)target[0]=dbIndSurMesh;
                                    target[1]=dbIndSurPtab.
      vc1     projectionVector; if NULL: normal projection
    see UTRA_def_...

int UPRJ_app_pt	(	Point *	p2,
		Point *	p1
	)

    apply projection to a point.
    see UTRA_app_pt UT3D_pt_projptpl UT3D_pt_intptvcpl_ UT3D_ptDi_intptvcpln

int UPRJ_app_vc	(	Vector *	v2,
		Vector *	v1
	)

apply projection to a Vector. using plane prj_tg, prj_vc.

int UPRJ_app_ci	(	CurvElli *	e2,
		Circ *	c1
	)

    apply projection to a Circle.
    see UT3D_el_projcipl

int UPRJ_app_el	(	CurvElli *	eo,
		CurvElli *	ei
	)

    apply projection to a Circle.
    see UT3D_el_projcipl

int UPRJ_app_plg	(	CurvPoly *	cvo,
		CurvPoly *	cvi,
		Memspc *	objSpc
	)

int UPRJ_app_bsp	(	CurvBSpl *	cvo,
		CurvBSpl *	cvi,
		Memspc *	objSpc
	)

apply projection to a Polygon

int UPRJ_app__	(	void *	objo,
		int *	otyp,
		int *	oSiz,
		int	iNr,
		void *	obji,
		int	ityp,
		Memspc *	objSpc
	)

    apply projection to struct; NOT object.
    init with UPRJ_def__
    Storage:
      Normale structs werden nach objo ausgegeben;
      ObjGX-Records: ObjGX-Records werden nach objo ausgegeben; die
        zugehoerigen Daten (structs) werden in objSpc gespeichert.
   
    Extern Vars:
      APT_prim_seg      solutionNr; 0=first.
    Input:
      oSiz   size of objo; wird recursiv verkleinert !
      otyp   form of obji; muss also bei Surface auch Typ_ObjGX sein !
      iNr    Anzahl structs to transform
    Output:
      oSiz   freier Restplatz in objo
      objSpc fuer Daten (structs) von oGX-Objekten; kann f. structs NULL sein

int UPRJ_app_obj	(	void *	objo,
		int *	oSiz,
		void *	obji,
		Memspc *	objSpc
	)

    UNUSED - see UPRJ_app__
    apply projection to struct or object.
    init mit UPRJ_def_.. erforderlich !!!
    Storage:
      Normale structs werden nach objo ausgegeben;
      ObjGX-Records: ObjGX-Records werden nach objo ausgegeben; die
        zugehoerigen Daten (structs) werden in objSpc gespeichert.
   
    Input:
      oSiz   size of objo; wird recursiv verkleinert !
      obji   (ObjGX*)  (NUR (ObjGX*) moeglich !)
    Output:
      oSiz   freier Restplatz in objo
      objSpc fuer Daten (structs) von oGX-Objekten

int UPRJ_app_oTab	(	void *	objo,
		int *	oSiz,
		void *	obji,
		Memspc *	objSpc
	)

    einen oGX-Block resolven
    Input:
      obji parentRecord (ObjGX-Record) dessen form ebenfalls oGX ist
