/*
      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
      you right-click, you are right clicking this div and not the image. This prevents users from
      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
      events as usual.
