A hello world application for wayland
This is a wayland hello world application. It uses the wayland
client library and the wayland protocol to display a window in
a wayland display server. It sets the cursor icon and receives
pointer input, exiting the program when clicked, so that it
is a complete input/output example.
Wayland configuration is verbose, so the code is split into a
helper module, which does all the job and the main module, which
describes in a high level each step configuration and operation.
