Radius+MittelPunkt+Radius

Macht Sinn. Ich war mir dessen auch vorher schon bewusst aber hab kein Plan gehabt das zu eliminieren.

Vielen dank PureLust & Kaeru!

jaa... aber mach dann noch die "sinnlosen" Berechnungen weg :

#Radius = #Height / 2 - 0.333

#CenterY =  (#Height / 2) + #WhiteSpace - 0.333
