Struct ShownLines 

pub struct ShownLines(pub Vec<(u32, f32)>);

VM.3f: the window’s lines, top to bottom, each with its height in line-heights (1.0 for an ordinary row). The host builds it from the walk it paints with; this type owns vim’s rule for which of them H / M / L mean, so the keyboard motion and the host’s JumpViewport action answer from one place. Checked in vim 9.2: a count past the window clamps to the far edge, and M is top + (lines shown − 1) / 2 — half the lines SHOWN, so a short buffer’s middle, not the window’s.
