Pile cotticing does not work

1) if you blazon a 'pile colourX cottised colourY', the cottising does not display properly: instead of appearing outside the charge with small gap of the field showing between the cottis and the charge, the cottis line appears slightly inside the charge, with the charge's edge showing: it looks like a double fimbriation. You can see this easily with e.g. "sable, a pile argent cottised gules".

2) On certain shield shapes you can see the bottom edge of an inverted pile e.g. "sable, a pile inverted argent fimbriated gules", on a swiss shield. You can see the fimbriation line at the tip of the shield, which should not appear. The
problem is more obvious with the blazon "sable, a pile inverted argent cottised gules", but this is only because the cottising is displaying incorrectly as per problem 1). Hope that is helpful, thanks.

首先，在受影响的盾牌形状上使用示例纹章描述 "sable, a pile argent cottised gules" 和 "sable, a pile inverted argent fimbriated gules" 重现该问题。没有指定文件或测试，因此请跟踪处理 piles、cottising 和 fimbriation 的渲染路径；完成的标准是 cottis 位于 charge 外侧并与其之间留有 field gap，且 inverted piles 不显示底边。
