public boolean contains(float x, float y, float w, float h) Implements abstract com.sun.javafx.geom.Shape.contains. Doc from com.sun.javafx.geom.Shape.contains. Tests if the interior of the `Shape` entirely contains the specified rectangular area. All coordinates that lie inside the rectangular area must lie within the `Shape` for the entire rectanglar area to be considered contained within the `Shape`. The `Shape.contains()` method allows a `Shape` implementation to conservatively return `false` when: the `intersect` method returns `true` and the calculations to determine whether or not the `Shape` entirely contains the rectangular area are prohibitively expensive. This means that for some `Shapes` this method might return `false` even though the `Shape` contains the rectangular area.
