enumFillRuleWinding

static final int enumFillRuleWinding

winding fill rule (aka non-zero winding rule). A point is in the polygon interior if a winding number is not zero. To compute a winding number for a point, draw a ray from this point to infinity. If N is the number of times the ray crosses segments directed up and the M is the number of times it crosses segments directed down, then the winding number is equal to N-M.
