  Version      : 2.3
  Release Date : 22.07.1995


  Requirements
  ~~~~~~~~~~~~
  - OS V2.04+ (V37)+ and its libraries
  - superviewsupport.library V5+


  Description
  ~~~~~~~~~~~
  FastILBM24.svobject is an external Library-Module for the
  superview.library V5+.

  It has especially been written to allow fast and "low-memory"
  loading and dithering of ILBM 24 Bit graphics.

  This means, that no compressed or uncompressed 24 Bit data will
  be completely loaded into memory, but directly be dithered
  to HAM6/8, so that even people with less memory and no graphics
  card will be able to view those nice 24 Bit graphics.

  May be deactivated, even if installed; may be switched between
  HAM6 and HAM8; allows increasing/decreasing of internal cache buffer.
