    Utility to compute the aspect, plot width/height and sizing_mode
    behavior.

    Args:
      width (int): Plot width
      height (int): Plot height
      frame_width (int): Plot frame width
      frame_height (int): Plot frame height
      explicit_width (list): List of user supplied widths
      explicit_height (list): List of user supplied heights
      aspect (float): Plot aspect
      data_aspect (float): Scaling between x-axis and y-axis ranges
      responsive (boolean): Whether the plot should resize responsively
      size_multiplier (float): Multiplier for supplied plot dimensions
      logger (param.Parameters): Parameters object to issue warnings on

    Returns:
      Returns two dictionaries one for the aspect and sizing modes,
      and another for the plot dimensions.
