- Added SetNextItemWidth() helper to avoid using PushItemWidth/PopItemWidth() for single items.
Note that SetNextItemWidth() currently only affect the same subset of items as PushItemWidth(),
generally referred to as the large framed+labeled items.
Because the new SetNextItemWidth() function is explicit
