Yes, very much so. My main use case is also image processing.

It would be useful if you could compare your work to other implementations,
such as:
 * Phil Endecott's related proposal last year, and the ensuing discussion:
http://lists.boost.org/Archives/boost/2007/04/120082.php
 * Dr. Dobbs, "Fixed-Point Arithmetic Types for C++,"
http://www.ddj.com/cpp/184401992

How are multiplication and division handled?

Is overflow detection and/or saturation arithmetic supported?

Cheers,
