[terrain] 构造规则：{NEW:BEACH !,Chw,Khw,Khs,W*,S*,Xv,Qx*,A*,_* W* fl

构造规则：{NEW:BEACH !,Chw,Khw,Khs,W*,S*,Xv,Qx*,A*,_* W* flat/shore}

它用于构造海滩，此处海滩指的是浸在水中、陆上透过水能看到部分。

• [*]TERRAINLIST：!,Chw,Khw,Khs,W*,S*,Xv,Qx*,A*,_*（不是荒废的城堡、荒废的主楼、水类、沼泽类、Void、裂隙、冰雪地类的地形）
• [*]ADJACENT：W*（水类地形，包括深水、浅水、浅滩、礁石）
• [*]IMAGESTEM：flat/shore

包含四个旋转模板，每个模板产生6条，总计24条规则。

先后次序依次是6条内凹(concave)、6条外凸(convex)、6条内凹(concave)、6条外凸(convex)。

需要的文件名类似{IMAGESTEM}-concave-@[email]R0-@R1.png[/email]、{IMAGESTEM}-convex-@[email]R0-@R1.png[/email]。

层值是-500，标记类似“beach-@R0-@R5”，beach字符只有此规则有，因此只要地形满足条件，这规则都会被用上。
