# One of several prefs affecting the maximum area to pre-render when animating
# a large element on the compositor.
# This pref enables transform (and transform like properties) animations on a
# large element run on the compositor with rendering partial area of the
# element on the main thread instead of rendering the whole area. Once the
# animation tried to composite out of the partial rendered area, the animation
# is rendered again with the latest visible partial area.
