Dear Maintainer,

A long time ago GraphicsMagick (and ImageMagick) were built with the
--quantum-depth option set to 8.  Both are now being built with it set
to 16.  I think that change was quite reasonable and a good default.

I'm requesting to have an alternative package built with quantum depth
set to 8.  This will reduce memory usage by half and make operations
faster for 8 bit (per channel) images (the vast majority).

The current package names already encode the quantum-depth option used
and in the case of ImageMagick, here's even packages built with and
without hdr support.  Because of this, I feel that a lot of the work
is already in place.

I'm happy to provide patches if this request meets with positive
interest and someone is willing to review the patches.

Best wishes
David
