Meta: Event Property Hooks

[Rick Waldron]

Implement the ability to specify properties of event.originalEvent to be moved over to event.* for specific event types, without the performance sacrifices of copying all event.originalEvent properties or adding to the globally used jQuery.event.props list

Will be particularly useful for newer events introduced by HTML5 JavaScript APIs that have special properties that are ignored by jQuery.event.fix() when it copies the jQuery.event.props array.

Ex.

Drag/Drop API has "dataTranser", touch event props, messaging event props, Custom data properties

Ultimately, this will allow end devs to write less code and we can stop recommending the extension of jQuery.event.props

Can be stored as simply as shown here ​http://jsfiddle.net/rwaldron/JxdNj/

Ticket #6942 is another example of when this could be useful. Right now we run all events through the same jQuery.event.fix paths regardless of event type, which is probably causing performance issues in cases where event frequency is high such as mousemove.

Let's try to get this in 1.7.

+1, I like the concept but am concerned about size issues and the temptation to define every property for every event type. Worth an exploratory implementation though.
