A listed font is compared only from its .shx file or the embedded stroke
font of that name; no TrueType or alias stand-in. Objects with a diagonal
over five times the selection's mean diagonal join no group. The created
MTEXT height is the mean of the character sizes. Text styles look a bare
font name up as .shx first, and a missing .shx name never draws with a
TrueType face. TXT2MTXT measures TEXT to its last inked stroke.
