Ellipse positioning fix

This won't fix  all ellipses.
But it fixes some problems till we ( ehm... you ) won't use ctx.ellipse() instead of ctx.arc
Anyway this is the list of visible fixes:
In the svg import 127 it fixes the little ellipses around the helmet, sunglasses and the other.
In the svg import 90 it fixes the belly and the bracelet of the teddy bear ( the ears are still a big problem for me, working on that )
in the svg import 130 it fixes the black part of the girl's eye
in the svg import 137 it fixes terminator ( or arnold's ) dots on sunglasses and forehead.
