QHeaderView: fixing selection of reordered rows and columns
The old code incorrectly calculated visual region for a selection (specified by
QItemSelection object) in case of reordered / swapped rows or columns. It used
the leftmost and rightmost (upmost and downmost for vertical mode) logical
indexes directly. However some middle logical index (in case of reorder) may be
the leftmost or rightmost visual index. In such cases the repainting didn't
work properly. This fix first checks whether reordering / swapping is in use.
If it isn't (ie visual=logical) we use code similar to the old code. Otherwise
the new code scans all selected logical indexes, translates them into visual
ones and gets the correct leftmost and rightmost indexes.
[ChangeLog][QtWidgets][QHeaderView] Fixed a repainting issue when items had been reordered.
