Follow-up to the kerning rule: on the real corpus (ms6: titles condensed by 1 pt from the
master's title style) PowerPoint kerns condensed text, and a closer probe agrees for -0.6, -1,
-1.5, -2 and -3 pt (only -1.2 and -2.5 pt came out unkerned, which no simple rule explains). Only
spacing out by 0.6 pt or more now switches kerning off for the box. ms6 slides 2/7: 4.97 -> 6.44
-> back to 4.97, 7.05 -> 8.10 -> 7.05.
