The maximum character width.  That's why he proposes to use the width of
an "M" for this.

Probably to know how many characters fit into a line.  With a
proportional font.

He wants the width of a default font "M" (where the default fount could
be proportional) filtered by the frame it appears on and the remapping
specified for the buffer the character appears in.
