make Combining
Returns Path that is the result of applying the Op to the first path and the second path.
The resulting path will be constructed from non-overlapping contours.
The curve order is reduced where possible so that cubics may be turned into quadratics, and quadratics maybe turned into lines.
Return
Path if operation was able to produce a result, null otherwise
Parameters
one
The first operand (for difference, the minuend)
two
The second operand (for difference, the subtrahend)
op
The operator to apply.
