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

       switched::configure canvasLabelObject ?options?
              Configures  a  canvasLabel  object  or returns all the options with their current values if no
              options are passed as parameters.

       switched::cget canvasLabelObject option
              Returns an option value for the specified canvasLabel object.

       stooop::delete canvasLabelObject
              Deletes the specified canvasLabel object.


OPTIONS
       -anchor value
              Specifies the anchor position of the rectangle and  the  text,  relative  to  the  positioning
              point.  The behavior is similar to the -anchor option of the canvas text item, except that the
              rectangle is taken into account. The default is center.

       -background color
              Specifies the background color of the bullet rectangle, as in the -fill option of  the  canvas

       -bordercolor color

              item. The default is black.

       -borderwidth value
              Specifies the border width of the rectangle, as in the -width option of the  canvas  rectangle
              item. By default, the width is 1 pixel, which is the minimum width.

       -bulletwidth value
              Specifies the width of the rectangle placed to the left of the text. Defaults to 1_.

       -font value
              Specifies the font of the text, as in the -font option of the canvas text item. The default is

       -minimumwidth value
              The total label width will not go below the specified value, but may be larger  if  the  label
              text requires it.

       -padding value
              Specifies  how  much space to leave between the text and the closest rectangle edge. Units are

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

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