XCLIP clips block and xref references to a rectangular, polygonal or
closed-polyline boundary (Invert clip, ON/OFF, Delete, generate Polyline;
Clipdepth is ignored in 2D). The boundary is Insert::clip, in block
coordinates, so it follows its reference; other references stay whole.
Clipped references are drawn, plotted and framed (XCLIPFRAME 0/1/2) cut
to the boundary, attributes included, and their extents are cut to it.
DXF and DWG read and write it as the reference's ACAD_FILTER/SPATIAL
SPATIAL_FILTER; filters the model can't hold stay foreign data. Gap F2.

* 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
