[x3d-public] passive vs. active mouse isOver event

I changed freewrl so it would gen events in this case.
Mobile devices with touch sensors dont normally do isOver. I changed freewrl so it could - with a persistent cursor. And a way to pedal the cursor so fingers dont obscure the target. And multitouch.

I noticed that cobweb does not generate an isOver TouchSensor event when the pointing device is not moved actively but the sensed geometry itself moves under the mouse pointer. At first this was surprising to me but after reading


this seems to be the expected behaviour since active mouse movement is required to generate events.

Do other browser behave the same way ?
