[x3d-public] highlighting on isOver, freeWrl

[Andreas Plesch]

Got it. It works fine. Perhaps the desktop/mouse and the mobile/touch
behaviours have to diverge more. For touch it seems necessary to have
a toggle to switch on isOver behaviour while dragging/moving but for
desktop it is more natural to just move the pointer without pressing a
button. This is probably the spec. intended behaviour to generate
isOver events. Another good UX topic !

Thinking about it, for touch it may be possible to have isOver
behaviour as long as the finger is moving. Tapping without moving
could be then a click, and tapping then moving could be dragging.

We could check how web browsers do it,
