The canvasLabel class brings some Tk label widget functionality to the canvas text item, such as a background and a border.
The canvasLabel is built with a bullet rectangle on the left side of the text. The relief changes according to the select state, with a traditionally sunken relief when selected.
The label has a specific tag, which can be used to retrieve the coordinates of the object or move it, thanks to the canvas facilities.
