A glyph's metrics for vertical writing, in glyph space units (thousandths of text space).
public readonly record struct CidVerticalMetrics(double VerticalAdvance, double PositionX, double PositionY) : IEquatable<CidVerticalMetrics>
ISO 32000-2 §9.2.4 (Figure 55) and §9.7.4.3: from the CIDFont's W2, else DW2 (default [880 −1000]) with
v.x half the glyph's width. In vertical writing the glyph is painted with its horizontal origin at the current point minus v
(scaled by the font size), and the pen moves by w1.
