And please wrap the main commit message at max 74 characters, otherwise `git log` and similar look so weird.
## Naming Convention
There are three types of coordinate systems: surface, output and layout - for
which the variables (sx, sy), (ox, oy) and (lx, ly) are used respectively in
line with wlroots.
With the introduction of the scene-graph API, some wlroots functions also use
node coordinates (nx, ny) but we prefer (sx, sy) where possible.
