Changes to support client-side image pre-caching in the region. This
  commit adds an additional calling sequence to the DynamicTexture data
  and URL calls. The new interface allows a dynamic image to be loaded
  into a specific object face (rather than the mandatory ALL_SIDES
  supported today.
  This is in part fulfilment of ticket #458.
