       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.

       stooop::newcanvasLabelcanvas ?options?
              Creates a canvasLabel object in the specified Tk canvas.  The  canvasLabel  object  identifier  is
              returned (referred to as canvasLabelObject in this document).

       switched::configurecanvasLabelObject ?options?
              Configures a canvasLabel object or returns all the options with their current values if no options

       -justify value

       -minimumwidth value

       -padding value
              Specifies  how  much  space  to  leave  between the text and the closest rectangle edge. Units are
              identical to those specified in the canvasCOORDINATES manual section.

       -scale list
              List of 2 floating point numbers used to set the scaling factor in the x and y  axis.  Scaling  is

              Sets the label state.

       -selectrelief value
              Either flat, raised or sunken. Specifies the 3D effect desired for the text area when the label is

       -stipple bitmap
              Specifies  the  stipple  pattern  filling  the  rectangle, as in the -stipple option of the canvasrectangle item. There is no bitmap by default.
