Linetype patterns (e.g., dashed or dotted lines) are tied to the viewport’s scale. When a viewport is zoomed in or out, the visual length of the dashes scales proportionally with the geometry.

Expected Behavior: Linetype patterns should scale inversely to the viewport scale. A dashed line should maintain its intended visual density (appearance) regardless of the viewport’s magnification level. This also matches the behavior of print preview / printing / PDF export.
