Sometimes XT can hit this assertion

[baconpaul]

One of my code paths is doing an end without a begin. Debug before we ship.

   #if JUCE_DEBUG && ! JUCE_DISABLE_AUDIOPROCESSOR_BEGIN_END_GESTURE_CHECKING
    // This means you've called endChangeGesture without having previously
    // called beginChangeGesture. That might be fine in most hosts, but it
    // would be better to keep the calls matched correctly.
    jassert (isPerformingGesture);
    isPerformingGesture = false;
   #endif

I will leave this open but one case was

select slider
drag
rmb

and i have fixed that case in an upcoming branch (where the RMB didn't set type to no edit)

close this if i don't find others over the next month.
