This adds a new API for allowing a widget to optionally specify a function that can be used for determining whether or not a given point is over the widget. By default, a function that simply checks the bounding rectangle is used. This has been implemented for all existing widgets with non-rectangular bounds (other than `Text`) including: - `Line` - `Oval` - `PointPath` - `Polygon` - `RoundedRectangle` - `Triangles` Each of the containing modules also provide helper functions that may aid in the implementation of custom widgets.
