 always expected to be present.
 
 Core interfaces:
-\begin{itemize}
-\item wl_display: provides global functionality like objecting binding and fatal error events
-\item wl_callback: callback interface for dnoe events
-\item wl_compositor: core compositor interface, allows surface creation
-\item wl_shm: buffer management interface with buffer creation and format handling
-\item wl_buffer: buffer handling interface for indicating damage and object destruction, also provides buffer release events from the server
-\item wl_data_offer: for accepting and receiving specific mime types
-\item wl_data_source: for offering specific mime types
-\item wl_data_Device: lets clients manage drag & drop, provides pointer enter/leave events and motion
-\item wl_data_device_manager: for managing data sources and devices
-\item wl_shell: shell surface handling
-\item wl_shell_surface: shell surface handling and desktop-like events (e.g. set a surface to fullscreen, display a popup, etc.)
-\item wl_surface: surface management (destruction, damage, buffer attach, frame handling)
-\item wl_input_device: cursor setting, motion, button, and key events, etc.
-\item wl_output: events describing an attached output (subpixel orientation, current mode & geometry, etc.)
-\end{itemize}
