Setting min/max options does not update view

[maenu]

If you change the min or max options, the visual state of the slider does not get updated, but it should.

Example:

$("#slider").slider({
    range: true,
    min: 0,
    max: 3,
    values: [1, 2]
})
...
$("#slider").slider("option", "min", 1); // the bar still looks like -|--|-
...
var values = $("#slider").slider("option", "values");
$("#slider").slider("option", "values", values); // this is an ugly workaround, but triggers the change event

I'd propose either to catch that in _setOption and handle as setting the values, but not trigger the change event - since only the min/max changed, and not the values - or add a refresh method like the button has one.

Triggering change in any case would be safest as the value might change as the result of the min/max change. This would also be consistent with the design of the change event. From specs on ​http://wiki.jqueryui.com/Slider "triggers when the slider has stopped moving and has a new value (even if same as previous value)"

I'm inclined to say that the behavior for the change event should be modified. We have a tendency to not trigger change events if values don't actually change (at least in newer widgets). We should probably be consistent here and modify this for 1.9.

This is still relevant in 1.9. Here's a fiddle showing the problem described ​http://jsfiddle.net/tj_vantoll/pgKfb/.
