[webkit-help] isOverLink() function in android-webkit

[Robin Cao]

If you want to know how mouse events are handled internally, the following
function should be a good start point.

HitTestResult EventHandler::hitTestResultAtPoint(const IntPoint& point, bool
allowShadowContent, bool ignoreClipping)

You can set a breakpoint there, or search this function in the project.
