- or migrating a TOutline to a TTreeview many years too late.

| HighDPI themed Delphi 10.4 TOutline and TTreeview |
The task to migrate from a working old TOutline to a TTreeview was long overdue in a small program I almost use daily - and its code had not really been touched since it was created.
TOutline was included in Delphi 1 back in the Win 3.1 days, and since Windows did not have any Treeview/Outline in its common controls it was purely VCL, not a wrapper.
It has for many years been advised to not use TOutline for any new projects, but instead use TTreeview or similar - but once in a while I do bump into this component - and this time I thought I would write a small and incomplete migration guide.
