nvrl 5a8e73657c feat(gui): justify the gallery rows and keep the thumbnails on screen
The Photos grid laid every photo out as a centre-cropped square. That is
why portraits showed black bars and why a panorama was unrecognisable at
tile size: the tile's shape had nothing to do with the photo's.

Rows are now justified. Photos are taken in capture order until they no
longer fit the target height, and the row is then scaled to land exactly
on the right margin, so each tile is its own photo's shape and nothing is
cropped or letterboxed. The last row of a day stays at the target height
rather than being stretched — a day holding two photos should look like
a short day, not like a layout bug. Ratios come from the daemon where it
has one; where it has not, the tile is laid out square and the day
re-flows once a decoded thumbnail proves the real shape, on the existing
debounce so a screenful of decodes costs one re-flow. Extreme ratios are
clamped, so one strip of film cannot decide what a row looks like.

Ctrl+scroll and Ctrl+± now move the target row height, and the grid is
tighter to match: 2 px gaps, smaller heading margins, a 6 px radius and
no card behind each tile, so the page reads as photographs rather than
as a deck of cards.

Thumbnails also stopped disappearing on scroll. The texture cache was
evicting in insertion order — which is precisely what a scroll back up
asks for again — so it is now least-recently-used and holds 1500 rather
than 600, which at the new density is several screens instead of under
two. A batch tops itself up with the photos just past the rows on
screen, in the direction of travel, and once the queue is short the
near-miss tiles are fetched rather than dropped.
