NSScroller won't always redraw itself

[Alexander Malmberg]

Hi,

If {NSScroller -setFloatValue:knobProportion:] is called with a changed
knobProportion but an unchanged floatValue the internal values will be
updated, but it won't redraw itself. The reason is that
-setFloatValue:knobProportion: sets the knobProportion and then calls
-setFloatValue: to set the floatValue and redraw, but the
-setFloatValue: thinks that nothing changed and doesn't redraw. I've
attached a patch that fixes this.
