Function rsvg::filter_func::drop_shadow_primitives

pub fn drop_shadow_primitives(
    dx: f64,
    dy: f64,
    std_deviation: NumberOptionalNumber<f64>,
    color: Color
) -> Vec<ResolvedPrimitive>

Creates the filter primitives required for a feDropShadow effect.

Both the drop-shadow() filter function and the feDropShadow element need to create a sequence of filter primitives (blur, offset, etc.) to build the drop shadow. This function builds that sequence.
