* bootstrap circle/ellipse size (fixes #670)
- do NOT zoom ellipse Y-size (only depends on vertical branch-distance)
- apply zoom first, then apply limit
- renamed limit awar (-> reset)
- scale limit fine-grained at lower border of range
- reduced max. limit to 30 (was 200)
- increase max. zoom to 30 (was 20)
- typo in GUI/help
* tests:
- changes accepted for Y-limit of ellipses
- changed used limit (to reproduce same results)
