A scene graph which can be used by a renderer such as sandcastle-vulkano to generate a display.
This crate is meant to take successful ideas used by various UI toolkits based on scene graphs such as Qt's Quick 2, EFL Evas, and GTK+ 4 GSK in a Rust native library. GSK is especially note worthy as the graph is immutable after construction which I believe fits well with Rust's memory model to start.
