Preferences › File Handling › Update Links only acted when a document
opened, so a linked image edited in another app while VectorCraft stayed
open kept its old pixels until Update Link in the Links panel, even with
Automatically chosen.
When the window comes back to the front, the active document's links
are now checked. With Automatically, changed files are read again; with
Ask When Modified, they are offered for update, once per change of a
file (keyed by path, size and modification time, since two saves can
share a time); with Manually, the Links panel shows them as modified.
Nothing is asked while a dialog is open.
