[webkit-dev] New web-facing CSS feature: -webkit-cursor-visibility: auto-hide

[Silvia Pfeiffer]

Is  -webkit-cursor-visibility just for video ? If so, I am personally very
much in favor of such a selector. It's a common feature of full-screen
video players, see e.g.
http://www.longtailvideo.com/support/forums/jw-player/bug-reports/31053/mouse-cursor-does-not-disappear-in-fullscreen-mode/or
http://forum.brightcove.com/t5/General-Development/Hide-Mouse-Pointer-in-Fullscreen/td-p/7128
 .

Here's a discussion by Chrome users:

It would be nice to get this through the CSS group quickly and implement
without the prefix.

Silvia.
