rect(row: number, width: number): CRect;

visibleRange(count: number, width: number, top: number, height: number): [number, number];

Returns the item index range intersecting the vertical viewport.

rowAt(x: number, y: number, width: number, count: number): number;

height(count: number, width: number): number;

contentSize(count: number, fullWidth: number, fullHeight: number, extent: number): CSize;

Start from the full viewport so obsolete scrollbars never lock in fewer columns.

Spatial navigation: vertical movement preserves columns; horizontal movement stays in its line.
