/// This function assumes that the styles and layout in the [`BaseDocument`] are already
/// resolved. Please ensure that this is the case before trying to paint.
///
/// The implementation of [`PaintScene`] is responsible for handling the commands that are pushed into it.
/// Generally this will involve executing them to draw a rasterized image/texture. But in some cases it may choose to
/// transform them to a vector format (e.g. SVG/PDF) or serialize them in raw form for later use.
