/** MarkerArrayPrimitive2D class
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.
