Message:

• Fixed: If control docked to panel owned by main form then it was possible to redock main form to conjoin form.
• Modified: Header title is now painted to canvas instead of use of TLabel. This will be necessary to draw rotated text later.
• Added: Length of header title is now reduced to not overlap to header buttons area.
