"100%" in Preferences ▸ Interface size multiplied the scale the display
reports, so on a 1080p screen whose system reports 200 % it still drew at
200 % (#456). A chosen size is now absolute, as PhotoCraft's UI Scale is: the
display's scale is divided back out, so "100%" is one screen pixel per point.
Auto is unchanged (the display's scale times GNOME's text scaling), and its
menu entry now shows the size it draws at. The menu offers PhotoCraft's sizes,
75–300 %.

* M14: interface size follows the system text scale
Preferences ▸ Interface size scales the whole interface (75–250 %, setting
`ui_scale`, control option `ui-scale`). Auto, the default, follows the
desktop's text scaling: on Linux and the BSDs the desktop app reads GNOME's
`text-scaling-factor` once at launch (through `gsettings`, with a 500 ms
limit; anything unusable counts as 100 %). With Large Text (1.25) on a 1×
display, the interface no longer draws 13 px labels that show their pixels
next to the system's text.
The size is egui's zoom factor, so `pixels_per_point` grows with it and page
rasters stay one texel per screen pixel (`canvas::render_scale`). It is
applied only when it changes, so a zoom set elsewhere (the test harness's
`pixels_per_point`) isn't undone every frame. egui's own ⌘+/⌘−/⌘0 interface
zoom is turned off so those keys stay page zoom.
Tests and headless screenshots keep 100 %: only the desktop app sets
`system_text_scale`. New labels are translated in every catalog, and the
catalogs' hashes in ATTRIBUTION.toml are updated.
* M14: offer a 50 % interface size
On a display the system reports at 200 %, the smallest size the menu offered
gave a 150 % interface (#456). 50 % brings it back to 100 %; settings and the
control channel already accepted it.
