LFO display doesn't update when automating LFO controls

The LFO display doesn't update when automating any or multiple LFO controls.

Switching to another LFO and switching back forces it to repaint and it updates to the current state, but still stays static. Moving the sliders manually though updates fine of course.

For LFO, I can see this:

So there's no attempts to repaint at all when this method is called (and it's called in SGE L927 and L1009 ).

Comparing with oscillator display, the similarly named repaintIfIdIsInRange actually does something. So we just need to apply the same methodology for the LFO display. On it!
