The approximate formula is: the initial bounding rectangle is inflated by pen width, and this result is multiplied by the miter limit, plus some additional margin to allow for end caps.
大概的公式为：初始周框会根据画笔宽度膨胀，而这个结果是乘以斜接限制，加上某些要考虑端点的额外边界。

The flywheel has a miter joint with the two end planes of the fan blade.
所述的飞轮与风叶轮两端面采用斜面贴 合。

The size of the returned bounding rectangle is influenced by the type of end caps, pen width, and pen miter limit, and therefore produces a "loose fit" to the bounded path.
