I don't know, but both Options and ShowRoot are implemented by
TCustomTreeView, not in the shell controls.

Delphi docs for reference:

http://docs.embarcadero.com/products/rad_studio/delphiAndcpp2009/HelpUpdate2/EN/html/delphivclwin32/ComCtrls_TCustomTreeView_ShowRoot.html

http://lazarus-ccr.sourceforge.net/docs/lcl/comctrls/tcustomtreeview.options.html

Options doesn't seam to exist in Delphi. Probably someone added this
option because he didn't know that the ShowRoot property existed.
