Hi folks,

Do we really think it's a good idea to add yet another implementation of filters?

We already have generic, NEON-optimized and WTF::ParallelJobs (which includes generic, OpenMP and libdispatch backends) implementations of this code, and now we're adding OpenCL too.

On the WebKit Project Goals page <http://www.webkit.org/projects/goals.html>, it states that:

"WebKit is an engineering project not a science project. For new features to be adopted into WebKit, we strongly prefer for the technology or at least the use case for it to be proven."

Correct me if I'm wrong, but we don't see much use of these features on the web. I understand that there's a bit of a chicken/egg problem where a feature won't be interesting to content creators until it performs well enough, but it seems like we could at least decide on a single path forward instead of repeatedly forking the code.
