Subject: [PATCH] ArchSectionPlane: Remove placeholders in getSVG and more
 clean up.

getSVG puts placeholders in the generated SVG code and replaces them
afterwards with length values. With the changes of the previous commits
this seems not to be necessary anymore.

I replace them in a separate commit so this change can be reverted easily.
