On the contrary, the legacy schema of MiniGUI-Processes uses the same

- Use `--enable-compositing` (default) to enable the compositing

MiniGUI-Processes (`--with-runmode=procs`).

In this version, we also enhanced the window manager of MiniGUI Core
to support some special main window types:
- Screen Lock. Use `WS_EX_WINTYPE_SCREENLOCK` extended window style
to create a screen lock. The main window acts as a screen lock will
have the highest z-order index in the system.
- Docker. Use `WS_EX_WINTYPE_DOCKER` extended window style
to create a docker. The main window acts as a docker will
have the z-order index lower than the screen lock in the system.
- Launcher. Use `WS_EX_WINTYPE_LAUNCHER` extended window style
to create a docker. The main window acts as a docker will
have the z-order index higher than the desktop in the system.
