* Build: line tables only in dev, no debug info for dependencies * Tests: one integration-test binary per crate Each crate's tests/*.rs becomes a module of tests/it/main.rs. Files that install process-wide state (the file io hooks, user aliases, SAVETIME and SAVEFILEPATH, user linetype and pattern files, registered fonts) stay their own test binaries. * xtask ci: nextest, tests without examples, one wasm check call

//! Grip editing acts on the whole selection, as in AutoCAD: a stretched grip drags the

//! coincident grips of the other selected objects with it, and Move/Rotate/Scale/Mirror
|
|
//! transform every selected object.
