(`usvg`) no `transform` property for Non-Group -> by design?

Hi. noticed relative transform does not exist per node, wondering if this is by desig, as the tree will be altered while parsing.

Even if it is, I think we can still have rel transform per node, while that rel transform might not refer to original svg tree's certain parent element, but simply stating relative transform relative to the post-tree parent.

#[derive(Clone, Debug)]
pub struct Path {
    ...
    pub(crate) transform: Transform,
    pub(crate) abs_transform: Transform,
    pub(crate) bounding_box: Rect,
    pub(crate) abs_bounding_box: Rect,
    pub(crate) stroke_bounding_box: Rect,
    pub(crate) abs_stroke_bounding_box: Rect,
}

I can do inverse + multiply, but would be nice to have it from the lib itself.

Yes, a transform can only be present on groups. An ability to set a transform directly to elements is kinda a syntax sugar in SVG. Like many other things. I.e.

<rect opacity="0.5" transform="translate(10)"/>

would be re-interpreted as

<g opacity="0.5" transform="translate(10)">
    <rect/>
</g>

Because this is how it is expected to behave in SVG. Mainly due to masks and filters.

PS: judging by you recent issues, I would suggest that resvg/usvg isn't the right library for you. The whole point of it is to abstract the SVG internals, not to preserve them. usvg is not an SVG parser.
