    argument: yes

    description: >
      If an end size is provided, then this is the starting size, and
      size is interpolated over the duration of the filter from start
      to end size.
      If the keyframable property "blur" is provided, then this is ignored, and
      "blur" is used instead.
      This parameter also affects the size both horizontally and vertically
      simultaneously, in amounts proportional to the horizontal size and
      vertical size parameters.
