Relative zoom amount
Controls the Reaper arrange-view scroll position and zoom level.
Two styles of command are available for each axis:
startScrollLeft()/stopScrollLeft(),startZoomInX()/stopZoomInX()etc. — models a held button. Scrolling/zooming continues while active and stops when released, matching the behaviour of hardware controller buttons. Mirrors how Transport.startRewinding works.scrollX(value)/zoomX(value)etc. — sends a single relative step to a rotary encoder address. Positive values move right/down/zoom-in; negative values move left/up/zoom-out. Larger magnitudes scroll/zoom further per message.Reaper does not send feedback for any scroll or zoom command, so these are fire-and-forget.
