Comment 1 for bug 994621

The fix to this problem could be regarded as a workaround. When animating camera changes (rotations, zooming, panning) the current ROI is updated very often (i.e. every render pass) and mostly in vain as before the new image retrieved for the ROI can be displayed, the ROI already changed again. Thus camera change events are now only fired when the camera animations finished, thus won't change again in the near future (next few render passes at least). This does not apply to the solar rotation tracking however, where with every automated rotation the ROI actually changes.
