ConstThe frame owns position, size and zoom; the drawing is a viewBox of the movable's unzoomed
bounds stretched to fill it, so a resize re-evaluates the geometry (adjust values are ratios,
and the shape stretches as it does in Excel) and zoom thickens lines as Excel's does. A custom
geometry is evaluated like a preset, from the definition the file states.
A shape in the sheet: its geometry as one SVG that fills the movable's frame, its text at the geometry's text rectangle, and its adjustment handles while it is selected.
