  11    RTG display Mode ID construction:
  12
  13    nnnn xx yy
  14
  15    nnnn - Number of card in the system, counting starts from 0x0010.
  16      xx - sync index
  17      yy - pixelformat index
  18
  19    xx and yy parts are obtained from the HIDD. Card number is maintained by
  20    graphics.library. Resulting mode ID is obtained by logical OR between these
  21    two components.
  22
  23    As i mentioned, RTG mode counting starts from 0x0010. Lower number means
  24    Amiga(tm) chipset mode. Modes from 0x0000 to 0x000A are officially defined
  25    in include/graphics/modeid.h, modes 0x000B - 0x000F are reserved, just in case.
  26
  27    Note that chipset mode IDs store modifier flags instead of sync/pixelformat object
  28    indexes. When chipset driver is implemented, this will need to be handled in a special
  29    way (by overloading mode ID processing methods in the driver).
