Description

After many tests, the functions outerWidth and outerHeight in dimensions.js, which make calls to innerHeight/innerWidth, and therefore to jQuery.fn.width or jQuery.fn.height, are the main bottleneck of many core interaction modules in jQuery UI.

After investigating, I'm seeing that there's a lot of room for improvement especially in jQuery.css (i.e. the :visible check is quite heavy), and I would like to see if there's anybody who can come up specifically with improvements for

outerWidth

outrHeight

dimension_patch.js can be included after jquery to test. A new jQuery function is added called $.size and some others overwritten. I guess it needs to be run through the test suite and debated and probably improved some more... but its a start.
