Displacement property is supported for point symbolizer in YSLD. It’s working well with no rotation. Below example is SVG black simple vertically oriented arrow, green square and red circle. All of them are rotated by 45 degrees (fig1.jpg):

        rotation: 45
        displacement: [0,0]
        symbols:
        - external:
           url: "./znaki_poziome/P-8a_2.svg"
           format: image/svg+xml
    - point:
        uom: metre
        size: 1.5
        rotation: 45
        symbols:
        - mark:
           shape: square
           stroke-color: '#3d8035'
           stroke-width: 0.1
    - point:
        uom: metre
        size: 0.25
        rotation: 45
        displacement: [0,0]
        symbols:
        - mark:
           shape: circle
           stroke-color: '#ff0000'
           stroke-width: 0.1

When I change the displacement property to [0,0.5] for arrow and circle, the SVG arrow symbol is displacement correctly but the circle and any other mark symbol will be shifted as if rotation were ignored (fig2.jpg):

    - point:
        uom: metre
        size: 4
        rotation: 45
        displacement: [0,0.5]
        symbols:
        - external:
           url: "./znaki_poziome/P-8a_2.svg"
           format: image/svg+xml
    - point:
        uom: metre
        size: 1.5
        rotation: 45
        symbols:
        - mark:
           shape: square
           stroke-color: '#3d8035'
           stroke-width: 0.1
    - point:
        uom: metre
        size: 0.25
        rotation: 45
        displacement: [0,0.5]
        symbols:
        - mark:
           shape: circle
           stroke-color: '#ff0000'
           stroke-width: 0.1

I would like the displacement property to work from mark symbols as for svg symbols, including the rotation of the symbols.
