Preface
-------
Since some time there's need for either an extension
or a complete rework of the IFF-ILBM file format: one can't
store chunky graphics and storing more than 256 colors
only is possible in a very unusual manner.
All that does slow down usage on graphics card-equipped
systems very much.
And IFF-ILBM's compression is not very efficient, too.
IFF-RGB8, IFF-DEEP and IFF-YUVN aren't good alternatives,
since they're mainly designed for 24 Bit images and/or make
use of uncommon compression algorithms and/or color spaces.
A first step to pass this by was SuperView's internal
graphics file format called "SVG" (SuperView Graphics),
but it was not an IFF file format and somewhat proprietary
in other terms, too.
That's why IFF-RGFX has been defined.
Look into the archive for developer information.
