Example to serve as a reference of a basic Wayland client using
Vulkan, contained in a single source file and with a minimal set
of dependencies.
Features incremental present (similar to swap_buffers_with_damage
from EGL) which is not commonly used by other Vulkan demos and is
useful to test the compositor.
Based on weston-simple-egl.
