#620

Todo:

  • Rendering of single planes
  • detection of format from filename and file extensions. I think the '.rgb565' extension does not really exist. The default extension should be 'rgb' and then we should look for '565' or somthing similar in the filname.
  • Differences
  • Big Endian 565
