* 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

//! DIMBASELINE spaces dimension lines by DIMDLI × the overall scale of the dimension it
|
||
//! continues: SETVAR DIM* overrides count, and DIMSCALE 0 falls back to the drawing's DIMSCALE
|
||
//! (issue #364). DIMSPACE's default spacing uses the same scale.
