# where desktop Linux is going, and a project that refuses floating-point in
# a timestamp is not going to make its first compromise for a display
# server. `wayland-dlopen` loads the Wayland client library at run time
# rather than at link time; `wayland-csd-adwaita` draws the window's own
# decorations on compositors that decline to draw them; `rwh_06` is the
# `raw-window-handle` 0.6 handle wgpu asks for when it makes a surface of
