  35. This interface communicates the content scale factor from the host to the plug-in view on

  36. systems where plug-ins cannot get this information directly like Microsoft Windows.

  37. 

  38. The host calls setContentScaleFactor directly after the plug view was attached and when the scale

  39. factor changes (system change or window moved to another screen with different scaling settings)

  40. When a plug-in handles this, it needs to scale the width and height of its view by the scale factor

  41. and inform the host via a IPlugView::resizeView().
