complete demo of web workers with transferrable typed arrays

This patch adds a demo that shows off WebKit's nascent support for transferrable Typed Arrays using postMessage between web workers. It can run synchronously, or with a varied number of worker threads, and with or without the new support for transferrable typed arrays, to demonstrate how performance varies across these scenarios. The application is a modified WebGL demo, taken from the Khronos repository (http://www.khronos.org/webgl/wiki/Demo_Repository).

corrected demo of web workers with transferrable typed arrays

Thanks for doing this work. I'm looking forward to seeing what this looks like running on top of the new Transferable support for typed arrays. However, there are several problems with this patch. First, this demo doesn't belong in the WebKit repository. You can submit a patch against the demos in the Khronos repository at https://www.khronos.org/bugzilla/ . Second, the patch is missing key new files like demo-multicore.js. Third, it replicates many files unused by the vertex-buffer-object demo such as o3djs/particles.js. I'm marking this patch r-. Please submit patches against this demo using the Khronos issue tracker.

Included missing files, removed unnecessary ones.

Thanks. Sorry about the file confusion, hopefully this is now corrected.

I've been doing this work under Dmitry Lomov's direction; he can indicate his intentions on Khronos vs. WebKit. I'm happy to submit it there instead.

Cool - I'll be happy to get this into Khronos repository instead if Ken thinks it belongs there :)

This has been checked into the Khronos repository. Closing.
