Bugfix: on Linux (X11) the inactive window was not getting mouse-move events.

This feature has been working in OSX for long - to see mouse-overs on buttons
from inactive windows (and tooltips) and allow a button to be active for
input right away.

Will need check by linuxers if this works satisfying. Also Windows now might
support this feature.
