/*!
|
|
* Overrides Apple's CAShapeLayer purely to change one method, so that hit-testing
|
|
* is done by checking whether the hit point lies:
|
|
*
|
|
* "inside ANY part of the layer's CGPath"
|
|
*
|
|
* This is used exclusively by SVGShapeElement, but in theory works for any SVG*Element class that
|
|
* uses CGPath to render itself.
|
|
*
|
|
* This is more useful than Apple's default implementation, but it might cause unexpected
|
|
* problems in other code (not that I'm aware of any - this override appears to be a common
|
|
* implementation, c.f. http://stackoverflow.com/questions/2944064/hit-testing-with-calayer-using-the-alpha-properties-of-the-calayer-contents
|
|
*
|
|
* TODO: should this layer be used in SVGEllipseElement, SVGPolygonElement, etc?
