Change the behavior of how :visible and :hidden work. :hidden is when an element is display none, a parent element is display none, or the element has a width of 0. :visible is when the element is not display none and all of its ancesotrs are not display none and its width is larger than 0. Fixes jQuery bugs #1349, #3265, and #3895.
