_________________________________________________________________DESCRIPTION
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 tra‐
ditionally sunken relief when selected.
The label has a specific tag, which can be used to retrieve the coordi‐
nates of the object or move it, thanks to the canvas facilities.

canvasLabel object identifier is returned (referred to as can‐

their current values if no options are passed as parameters.

Returns an option value for the specified canvasLabel object.
