patch to disable trough on mouse click

[Jörn Zaefferer]

Could you provide an example where this is useful?

Rather than adding an option, this should be achieved by checking the original event target in start. If not slider handle, cancel start. Depends on #5472 - slide start not cancelable

$("#slider").slider({

start: function(event, ui) {

return ( $(event.originalEvent.target).is(".ui-slider-handle") );

}

});
