There is no reason to find out where to update the headerview
if updates aren't enabled. Another approch I considered to skip the
whole calculation and just call update. I seriosly doubt that this
calculation and update of a particular QHeaderView rect will normally(*)
be faster than just updating everything.
However to be safe I have done the conservative fix.
(*) Normally but with many/fragmented spans in the headerview.
