Interaction of furs

I just wanted to let you know, something seems to have bugged on the Vairy input. If you input "Vairy ermine" or "Vairy Pean and Erminois" or "Vairy erminites ermine" or any other combination of the two furs, the output is visually glitched, the ermine tails are spliced and offset.

Thoughts - should ermine (and friends) be symmetrical about the vertical axis of the shield when laid out on the field? That would probably look nicer anyway...

No source file or test is named. Start by reproducing the listed Vairy combinations in Drawshield and compare their generated shield images, then trace the fur layout and SVG rendering path. Done means the ermine tails no longer appear spliced or offset and the intended symmetry behavior is verified for the reported combinations.
