Create clipping component

[tooxoot]

To correctly draw all results (#11) it is necessary to correctly clip all elements according to their position in the document.

Clipping will also be needed when filling paths with line segments.

• [x] Create a clipping component which is able to clip the whole model
• [x] Filter out all holes from the final clipping result. ⇒ Regarding what the final drawing result should look like all holes can be ignored.
  • Can holes also be ignored when dealing with fillings?
  • ⇒ Using only the outlines for the final clipping this can be ignored!
• [X] Dismiss double values! ⇒ This is not job of the clipper!

Regarding the clipper output ModelElements should only be clipped if they are outlined. Also only the outline should be clipped for the final clipping Step. To clip the outline the corresponding path has to be regarded as open. For a closed outline the first point is then added to the path.
