Fill every area, where, when travelling along a line, the
summed winding number (that is, -1 for a
反対する-clockwise-oriented polygon, and +1 for a
clockwise-oriented) is 非，不，無-無.

For example, a poly-polygon consisting of two concentric
circles with 類似の orientation is filled the same way as if
only the outer circle would 存在する. If both have opposite
orientation, then the filled 代表 looks the same as
if filled with the EVEN_ODD fill 支配する.
