Why don't you finish what you have done so that everybody can us it
and be happy?

> Since I last mentioned it here, I've moved it to Slang, so it is
> developed and built similarly to the regular BitBlt. Large portions are
> auto-generated from templates (namely many of the combination rules and
> pixel depth conversion), cutting down the amount of real code to be
> developed. While it can't yet run a Squeak image (well, not for
> long...), it can run some basic benchmarks and tests on itself. There
> are bugs, but it will at least run most of the internal benchmarks. The
> performance is promising, with most supported operations being faster
> than stock BitBlt, and a few being slower (these need to be
> special-cased). Some operations will not be supported soon, especially
> the WarpBlt functionality.

> I'm no longer working heavily on this, but do occasionally open it up to
> fix bugs, add docs, etc.
