How to draw a QML rectangle with different border radius

There are two ways of drawing a rectangle with different border radiuses / different roundings in pure QML:

1. Using the Canvas QML API, which is similar to using QPainter in C++ and the Canvas web API in JavaScript (CPU-based).
2. Using Shape QML API, which has a declarative paradigm, and better performance because it can directly draw with GPU, if your platform supports GL_NV_path_rendering.
