The SVG_SET_STROKE_LINECAP command can be used to specify the form of the path ends of the SVG object having the svgObject reference. If this attribute already exists, its value is replaced by the value passed as parameter.
The mode parameter must contain one of the following strings, handled by SVG:
- butt (default): standard
- round
- square
- inherit: inherited from parent object
If the mode parameter contains any other value, an error is generated.
