+            (Transform) contains the whole grid area, but will of course be combined
+            with the visible area (Viewport) when decomposed. Also a resolution-dependent
+            point reduction is used to not create too much grid visualisation data. This
+            makes this primitive highly view-dependent and it dynamically buffers
+            the last decomposition dependent from the Viewport used.
