/*!
|
|
* Overrides Apple's CALayer purely to change one method, so that hit-testing
|
|
* is done by checking whether the hit point lies:
|
|
*
|
|
* "inside ANY of my child sub-layers (some of which have over-ridden hit-testing too)"
|
|
*
|
|
* This implementation is used by SVGGElement (for obvious reasons!)
|
|
*
|
|
* 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
