//
//  1. Enforce API surface and semantic compatibility with 1.9.x branch
//  2. Improve the module's maintainability by reducing the storage
//      paths to a single mechanism.
//  3. Use the same single mechanism to support "private" and "user" data.
//  4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
//  5. Avoid exposing implementation details on user objects (eg. expando properties)
//  6. Provide a clear path for implementation upgrade to WeakMap in 2014

      Show context menu for image on right-click

      There is a div containing the navigation that spans the entire image and lives above of it. If

      saving the image or using other context menu actions with the image.

      To fix this, when we detect the right mouse button is pressed down, but not yet clicked, we
      set pointer-events to none on the nav div. This is so that the upcoming right-click event on
      the next mouseup will bubble down to the image. Once the right-click/contextmenu event occurs
      we set the pointer events back to auto for the nav div so it can capture hover and left-click
