* 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

//! An R2018+ MTEXT can carry an embedded object (group 101) that repeats its geometry with
|
|
//! other meanings: there, 10 is the X-axis direction and 11 the insertion point. AutoCAD writes
|
|
//! one for MTEXT with column settings, and the DWG bridge does too. Reading 11 from it as the
|
|
//! direction turned the text towards its own insertion point (#667).
