The returned iterator has the following methods...
reset() - resets the iterator to the start of the path
next() - advance to the next command
PathCmd cmd() - the current command
Point opIndex(idx) - get segment coordinates
When you use [] / opIndex the index is for indexing into the current
segment, so if the current command is a line, 0 will be the first point,
1 will be the end point. A cubic curve command can be indexed 0,1,2 or 3.
It is bounds checked in debug mode.
When all the commands are exhausted cmd() will return PathCmd.empty
Iterate the path one command / segment at a time.
