+            This primitive defines an array of markers. Their size is defined
+            in pixels and independent from the view transformation which makes
+            this primitive highly view-dependent. It is also transformation
+            invariant, so that the bitmap is always visualized unscaled and
+            unrotated.
+            It is used e.g. for grid position visualisation. The given Bitmap
+            (with transparence) is defined to be visible centered at each of the given
+            positions.
+            It decomposes to the needed number of BitmapPrimitive2D's, so it would
+            be efficient to handle it directly in a renderer.
