+
+            Caution: Due to old constraints (old core definitions) the
+            crop distances describe how the uncropped content is defined
+            relative to the current object size. This means that maTransformation
+            describes the current object size (the part of the object visible
+            with the crop applied). To get the original size and orientation
+            of the uncropped content it is necessary to calc back from the
+            current situation (maTransformation) using the crop values
+            to get to the uncropped original content.
+
+            Thus a transformation has to be calculated which will be applied
+            to the already existing content to get it to the uncropped state
+            and then this is masked with the current state (mask polygon
+            created from unit polygon and maTransformation).
+
+            At least in this primitive the units of the crop values are
+            already in the local coordinate system; in the core these distances
+            are defined relative to the object content size (PrefMapMode
+            and PrefSize of the content)...
+
+            Of course this is a primitive, so feel free to just ignore all that
+            stuff and use the automatically generated decomposition. Sigh.
