.. py:class:: ViewportTransform

   Viewport transformation for coordinate mapping.

   :ivar ox (int): Origin x-coordinate.
   :ivar oy (int): Origin y-coordinate.
   :ivar s (float): Scaling factor.


   .. py:attribute:: ox
      :type:  int
      :value: 0



   .. py:attribute:: oy
      :type:  int
      :value: 0



   .. py:attribute:: s
      :type:  float
      :value: 1.0



   .. py:method:: map_xy(x: int, y: int) -> tuple[int, int]

      Map the given (x, y) coordinates using the viewport transformation.

      :param x: The x-coordinate to map.
      :type x: int
      :param y: The y-coordinate to map.
      :type y: int
      :return: A tuple containing the mapped (x, y) coordinates.
      :rtype: tuple[int, int]



   .. py:method:: map_wh(w: int, h: int) -> tuple[int, int]

      Map the given width and height using the viewport transformation.

      :param w: The width to map.
      :type w: int
      :param h: The height to map.
      :type h: int
      :return: A tuple containing the mapped (width, height).
      :rtype: tuple[int, int]
