示例1: intersect3
bool intersect3(const Cubic& c1, const Cubic& c2, Intersections& i) {
bool result = intersect3(c1, 0, 1, c2, 0, 1, 1, i);
// FIXME: pass in cached bounds from caller
_Rect c1Bounds, c2Bounds;
c1Bounds.setBounds(c1); // OPTIMIZE use setRawBounds ?
c2Bounds.setBounds(c2);
result |= intersectEnd(c1, false, c2, c2Bounds, i);
result |= intersectEnd(c1, true, c2, c2Bounds, i);
bool selfIntersect = c1 == c2;
if (!selfIntersect) {
i.swap();
result |= intersectEnd(c2, false, c1, c1Bounds, i);
result |= intersectEnd(c2, true, c1, c1Bounds, i);
i.swap();
}
// If an end point and a second point very close to the end is returned, the second
// point may have been detected because the approximate quads
// intersected at the end and close to it. Verify that the second point is valid.

return result;
