      Add render mode in which values are drawn as recoverable 24bit colors. · f8c5c678

      With this you can pick an array component and draw that directly
      on the screen. Afterward, if you know the min and max, you read pixel
      values back and get a hold of the value at each pixel.
      
      TODO:
      * Lots of type conversion here, and in the end only using 24 bits
      of resolution. When and if we need more accuracy, flesh out
      the extensible conversion operator part.
      * Surface selection is based on the same concept (ident buffer)
      but that was written before VTK has extensible rendering (painters
      and passes). Eventually selection should be reimplemented to use
      this.
      * Would be great to demonstrate render into background followed by
      mouse overs.
