events are now always delegated (without any extra overhead)

This code also fixes a few bugs in the pinch event handling code. Please try the use-delegation.html page. It now works as expected (the same as with native touch events) and it's as efficient as the useDelegation=false code.

Hi Waldemar,

I'm still looking into the ramifications of this change, but I hope to pull it into master within a day or two.

thanks again for being awesome,
Bill

Hi Waldemar,

I'm very sorry, but I can't pull this into master as it stands right now. However, I'm hopeful we can figure out a way to pull in your technique in a different way.

The issue is being able to stop the event propagation ("bubbling up") if the developer wants to do so. I've created a test page on the event-target branch called donut.html to demonstrate the possible use case. The developer might want different handling of events on nested elements, and unfortunately, this is impossible with the technique you have proposed. (Please see Ben Alman's article, section 4.2 and section 4.3 about this issue -- however, he accidentally says event.preventDefault and he should have said event.stopPropagation.)

Perhaps there is a way for us to put your technique behind a settings parameter, somewhat like the original useDelegation setting? I would imagine that this would not replace useDelegation but would instead be exposed as a completely new settings parameter.

Also, if you do decide to revise this and submit a new pull request (which would be really, really great) please adhere to just a couple of conventions that are in the Touchy code now:

1. Please do not delete the comments showing the exploded example of the meta-programming loop.
2. Please prepend a dollar sign to all jQuery objects, like $target, so they are recognizable as such.

I very much appreciate your help and interest in the project. Please don't let this message prevent you from contributing a new solution. If you do send a new pull request, please send me your mailing address and shirt size in a private email, and I will send you a t-shirt! :)
