Yes but it depends on widgetset and theme. There is no absolute correct value, 
or the absolute value should be inspected at run-time somehow.

Yes, there is a border and the coordinates are relative to ClientWidth and 
ClientHeight. In Delphi they are relative to the total Width and Height.
All TWinControl descendants have this problem I am told.

If you have some good default values, please let me know.
