  * In order for these to be skinable we should define tool-tip and icon in a SkinPart.
   * They will be defined in the three implementing classes. Icons should be put in the same module as the views.

  * "Buttons" should be arranged correspondingly in the bottom left corner of the frame in the same order as described above.
  * Every icon should be scaled to look nicely inside the frame.
  * Media controls will be zoom-able along with the media frame but should not change their size as media frame's size changes.
-  * In order to do so, make the scene element of the MediaContentView a composite one and add the media scene element as well as the scene elements of the controls.
+  * In order to do so, make the scene element of the MediaContentView a composite one and add the media scene element as well as the scene elements of the controls to it. Every descendant of the MediaContentView (VideoContentView and AudioContentView for the time being) will provide a media element instead of just an element. Whether the media is playing or not will be kept in a value property inside the MediaContentView. This is needed for the ManipulationViews to update their state and appearance correspondingly (alpha values of colors for their scene elements).
  * The changing of the alpha values of the scene elements will be done by a MediaManipulationLogic that is common both for Audio and Video.
  * The managing of the media playback will be done by two other logics - AudioLogic and VideoLogic:
