Stroke is the widest feature that can be stroked, and it was applied to
each connected shape as a whole: a thick body with thin arms stayed one
filled area. Now a shape wider than Stroke somewhere keeps as its area
every disc wider than Stroke that fits in it, and each piece outside
those discs that reaches out of them at least one and a half times its
own width (and 3 px) is traced as a stroked center line. A line's end at
the area goes to the cut, so the line's cap closes the join. Corners and
edge slivers stay in the area, and a piece that cannot be traced stays
in it too. Shapes no wider than Stroke trace as before.
Each line keeps one width; without Fills, the area is still a 1 px
outline.

With logoColors named, Flat Logo measured how flat the image is against
the named colors. A solid pixel counts as flat only within 22 (RGB
distance) of one of those colors or white. Flat art whose named colors
were 20 levels off in every channel was refused as not flat, and the
refusal score of a gradient changed with the names.
The check now uses the image's own colors, found the same way as when
no colors are named. It looks for as many colors as are named, with
white, or as the Colors setting gives, whichever is more. How far the named colors are
from the image's colors no longer changes whether the image is refused.
This changes one existing behavior: an image with large areas of a
color that was not named used to be refused, and it is now traced in
the named colors.
