* M8: an arc's spread shadow gets room for its mitred corners

Rectangles, frames and ellipses grow by exactly their spread, so their
layers only make room for the spread itself; other shapes make room for
the mitre at sharp corners (up to four times the spread). An ellipse
with arc data (a pie slice, or a ring cut short) counted as an ellipse,
but its ends meet its sides in sharp corners: a spread of 25 on a slice
of 0.3 rad cut its shadow off at the layer's edge (up to 255 levels).

Only an ellipse that goes all the way round now grows by exactly its
spread. `figcraft_geom::full_sweep` is what `ellipse` already used to
tell a whole ellipse or ring from an arc, so the two agree.

* M8: an arc's mitred stroke gets room for its corners too

Review: `outline_reach` counted every ellipse as an outline whose stroke
mitres end on the grown box, the same mistake as the spread. A thin
slice with a 20-unit mitred stroke and a spread of 10 still had its
shadow cut off (255 levels). It now asks `grows_by_exactly_its_spread`,
which picks the same shapes and leaves arcs out.
