Commit 54f8fc4090 introduced the use of
wl_surface::set_buffer_scale, which is only available starting with
version 3 of the wl_compositor protocol. Because we already prefer
version 4 when available, this went unnoticed but broke versions 1, 2
and 3 when reaching the wl_surface::set_buffer_scale call.
This restores functionality for version 3 and properly document that
versions 1 and 2 are not supported anymore.

X Server
The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.
Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.
