Minor ticks on 1/x scales were using linear value interpolation between
harmonically-spaced major ticks. Because 1/v is highly convex, equal value
steps near a large major-value (left side of the first interval) map to tiny
physical steps, piling all ticks against the left wall. At a 1:1000 ratio the
first four minor ticks land at 0%/0%/1%/2% of the interval.
Fix: interpolate in position space (uniform physical spacing) for all
reciprocal intervals, matching how major ticks are laid out (also equal
physical steps) and matching the already-correct ∞-first-interval handling.
Also documents 1/x scale and ∞ max in README.
Lighter shorthand (^x, _x, {a/b}) rendered as glyph paths in the ГОСТ
font — no LaTeX engine, so typography and self-contained output are
preserved. Constructs nest (e.g. {m/s^2}, x^{1/2}). A marked-up unit is
sized to its true ink bounding box and centered in the unit box with
white space, fitting in both axes so tall fractions don't overflow.
Also fit plain units by measured glyph width rather than a per-character
estimate. Bump to 0.77.
