// should be enough then.

// in place because it was not possible/too expensive at that time to scale the wavelines with the
// view...
// With the VCL-PixelRenderer this will not even be used since it implements WrongSpellPrimitive2D
// directly and mimics the old VCL-Display there. If You implemented a new renderer without
