  This example demonstrates how a map's view can be
  adjusted so a geometry or coordinate is positioned at a specific
  pixel location. The map above has top, right, bottom, and left
  padding applied inside the viewport. The view's <code>fit</code> method
  is used to fit a geometry in the view with the same padding. The
  view's <code>centerOn</code> method is used to position a coordinate (Lausanne)
  at a specific pixel location (the center of the black box).
  <p>Use <code>Alt+Shift+Drag</code> to rotate the map.</p>
