# Convenience wrapper for the _interpolate function. Takes a
# single string or props.Node object in arg[0] indicating a target
# property, and a variable-length list of time/value pairs. Example:
#
# interpolate("/animations/radar/angle",
# 180, 1, 360, 1, 0, 0,
# 180, 1, 360, 1, 0, 0,

# 180, 1, 360, 1, 0, 0,
# 180, 1, 360, 1, 0, 0);
#
# This will swing the "radar dish" smoothly through 8 revolutions over
# 16 seconds. Note the use of zero-time interpolation between 360 and
# 0 to wrap the interpolated value properly.
