// This class iterates over the stroke geometry defined by a path and stroke. It automatically
// converts closes and square caps to lines, and round caps to circles so the user doesn't have to
// worry about it. At each location it provides a verb and "prevVerb" so there is context about the
// preceding join. Usage:
//
//     StrokeIterator iter(path, stroke);
//     while (iter.next()) {  // Call next() first.
//         iter.verb();
//         iter.pts();
//         iter.w();
//         iter.prevVerb();
//         iter.prevPts();
//     }
