+
+            This interface defines a poly-polygon, whose actual shape
+            is parameterized by a floating point value. This is
+            e.g. used to generically access the various clip polygon
+            generators for transition effects.
+
+            Since for every parametric poly-polygon, there is a set of
+            variations, which can easily be generated by simple
+            transformations or change in parameter range sweep
+            direction, objects implementing this interface only
+            generate <em>one</em> prototypical instance of the
+            parametric poly-polygon. Generally speaking, the main
+            effect direction should be horizontal, it should make
+            increasingly more area visible (transition 'in'), and when
+            there is a designated direction given, that should be
+            left-to-right.
+         */

+                Current parameter value to retrieve the corresponding
+                poly-polygon for. Permissible values for t must be in
+                the range [0,1].
+
+                @return a poly-polygon corresponding to the given
+                parameter value. The poly-polygon is interpreted as
+                living in the unit rectangle (i.e. [0,1]x[0,1]), but
+                is not necessarily constrained to completely lie in
+                this area (this very much depends on the actual effect
+                to be generated). Although, from a performance
+                perspective, it currently <em>is</em> advantageous to
+                try to keep the poly-polygon within these bounds (at
+                least if there are no hard reasons not to do so),
+                because then reversion or out transformations are
+                potentially faster to compute (see the
+                TransitionInfo::meReverseMethod member in
+                transitionfactory.cxx). Furthermore, if one of the
+                polygon modifications involve subtraction (also see
+                TransitionInfo::meReverseMethod), all generated
+                polygons should be oriented clock-wise
+                (i.e. traversing the polygon vertices with increasing
+                vertex index should generate a clock-wise movement).
