Guides reach the others. A guide someone dragged out of a ruler stayed on their own screen,
and so did moving, deleting or typing the position of one. Each of those now reaches everyone in
the template, and elements snap to the guide on every screen (see Collaboration).
For hosts: a guide edit is now a page-structure step. It still marks the document changed and
fires typograph_document_changed, as before.
Known limits
Undo of a guide edit can do nothing while editing together. It works once a later release
brings the canvas fix for it.
Typograph developers notes
TYP-919: adding (both rulers), dragging, deleting (Backspace/Delete) and the parameter bar's
position field record set_undo_structure() / set_redo_structure() instead of a page step:
guides are saved in the spread's page records, which element sync leaves to structure steps. The
ruler drag's stand-in guide is taken out before the step closes, so the step does not hold it.
Known limit until the next canvas pin bump: while editing together, undo of a guide edit can do
nothing. The undo snapshot can hold the guide elsewhere than the live spread, and the undo is
skipped as someone else's change; canvas Guide.copy() from the guide's native position (canvas
#254, TYP-919) fixes it, and the pin bump that brings it says so for users.
src/guidesteps.ts holds the guide edits that happen at once (deleting, typing a position).
