Constant WIDTH_MIN_PERMILLE
pub const WIDTH_MIN_PERMILLE: u32 = 1; // 1u32Expand description
Bounds of what a width can store, not of what a person may choose: a
group may be a sliver of a share up to any number of strips wide, the
strip scrolls. Windows’ own minimum and maximum sizes are the apps’ to
state (xdg_toplevel hints, a Tilo app’s compact layout); the only limit
of ours is WIDTH_FLOOR_PX.
