Copyright (C) 2015-2017 Paco Garcia, www.arakne.es
2017_07_30: added crossed corners
copy class of original object if exists
2017_08_09: rombus moved to From corners tab
2017_08_17: join circles not need boolen operations now
join circles added Oval
2017_08_25: fixed error in objects without style
in oval sets the minimal radius necessary
