JK3D 1c109be836 Headless pictures: no highlight left over from the picture before (#7225) (#7326) ...

* claim: #7225

* fix: headless pictures no longer keep the previous picture's highlight

Capturer::rgba_highlighted left the highlight slot empty when a picture had
no highlight. The renderer keeps its last highlight scene while the slot is
empty, so a selected edge's band drawn for one picture showed in the next
one on the same capturer. The depth tests share their capturers across test
threads, so they failed at random: an edge "192 of 612 px drawn", a washer
showing through its plate, a cut showing what lies behind it. A picture now
always gets a highlight scene of its own, empty without one.

Clearing the leak showed that a_selected_edge_on_a_grazing_face_draws_whole
passed at 88 degrees in a design of radius 30 only by counting the leaked
band: its reference line lies 143 mm behind the sheet's middle, past that
design's far plane, and drew nothing. The small design now holds the edge.

New test: a_picture_without_a_highlight_shows_none_of_the_one_before.
Full `--test depth` runs on Apple silicon: 10 of 10 failed before, 0 of 20
after.
