[path] Return the fixed-point bounds of the path
When analysing the stroke extents, we need the original fixed-point
extents so that we do not incur an OBO when we round-to-integer a second
time. We also need a more accurate estimate than simply using the control
points of the curve, so pass in tolerance and decompose until someone
discovers a cheaper algorithm to determine the precise aligned bounding
box of a bezier curve.
