Function emit_commands 

pub fn emit_commands(
    cmd_buf: &mut Vec<DrawCommand>,
    content_box: (f32, f32, f32, f32),
    is_inline: bool,
    view_box: ViewBox,
    shapes: &[SvgShape],
    opacity: f32,
)

Paints the shapes of an inline SVG into its content box.

Pushes a transform mapping the viewBox rectangle onto the content box with viewbox_meet_transform (letterboxing when the aspect ratios differ), emits one Fill per shape in document order, then pops the transform. The caller must have already pushed the box model: push_box_model translates block boxes to their content-box origin, and inline boxes push no transform (so is_inline paints in absolute coordinates). Paints nothing when the box or viewBox is degenerate.
