Drop 1:2.5: on a grid of 10 it steps by 4, which misses 10, so texts on
two elements 10 apart could never line up. Every remaining divisor is a
whole number, which tst_textgrid checks.
The divisor list and the snapping arithmetic move to the header-only
textgrid.h so the toolbar menu, the preferences page and the test share
them. The preferences page gets the same choice under Grille + Clavier;
QETApp::textGridChanged keeps every editor's toolbar button in step.
While element texts are dragged, the status bar names the text grid and
says to release Shift and hold Ctrl for free placement -- Ctrl+Shift
together is the pan shortcut.

Texts snapped to the folio grid, so the first drag of an off-grid label
pulled it sideways by up to half a grid step (discussion #1020). Texts
now snap to a fraction of the folio grid, chosen from a "Textes 1:N"
button in the View toolbar and a menu under Affichage: Off, 1:1, 1:2,
1:2.5, 1:5, 1:10. Because the step divides the folio grid, texts on
different elements still line up. Ctrl still places a text freely.
1:1 is the default and matches the previous behaviour. The setting is
stored in QSettings; nothing changes in saved projects.
All five text movers switch together: element texts, text groups,
texts moved with a selection, conductor texts and independent texts.
