Description
All of the support tests that run at doc ready, and possibly others, can instead be called lazily and then cached on jQuery.support. There are several advantages to this.
- It makes page loads faster.
- No doc ready needed
- No invisible body needed
- It is necessary for supporting Closure

Do you imagine this would fix this bug I just reported? http://bugs.jquery.com/ticket/11082? I was calling jQuery.is(':visible') right after loading jQuery. The function started performing slowly, as it thought $.support.reliableHiddenOffsets was false; actually, the variable was undefined, as it hadn't been initialised at doc ready yet.
So, with a lazy solution, I imagine the first call to jQuery.is(':visible') would trigger the feature detect to set $.support.reliableHiddenOffsets?
