Class FlatteningPathIterator

The accuracy of the approximation is determined by two parameters:

• The flatness is a threshold value for deciding when a curved segment is consided flat enough for being approximated by a single straight line. Flatness is defined as the maximal distance of a curve control point to the straight line that connects the curve start and end. A lower flatness threshold means a closer approximation. See {@link QuadCurve2D#getFlatness()} and {@link CubicCurve2D#getFlatness()} for drawings which illustrate the meaning of flatness.
• The recursion limit imposes an upper bound for how often a curved segment gets subdivided. A limit of n means that for each individual quadratic and cubic Bézier spline segment, at most 2ⁿ {@link PathIterator#SEG_LINETO} segments will be created.

Memory Efficiency: The memory consumption grows linearly with the recursion limit. Neither the flatness parameter nor the number of segments in the flattened path will affect the memory consumption.

Thread Safety: Multiple threads can safely work on separate instances of this class. However, multiple threads should not concurrently access the same instance, as no synchronization is performed.
