svg arrows using path syntax

[sugizo]

code

chess.svg.board(board = board, 
                              arrows = [chess.svg.Arrow(from_square, to_square) ] )

result

<line x1="247.5" y1="112.5" x2="265.45316561961454" y2="94.54683438038543" stroke="SpringGreen" stroke-width="9.0" stroke-linecap="butt" class="arrow" />
<polygon points="289.3180194846605,70.68198051533946 253.52073868709155,82.61440744786245 277.38559255213755,106.47926131290842" fill="SpringGreen" class="arrow" />

idea
nice to make it as path

reason

• just need define it as one syntax path, currently you need to define line and polygon syntax
• after zoom in, you can see intersection between line and polygon
• more customizeable using css with path (stroke color, stroke width, fill color, opacity, etc), while in polygon, you can only modify the fill color and opacity

thanks and best regards
