AutoCAD 2024 writes no group 290 on a SPATIAL_FILTER in a DXF and discards a file whose filter has one (measured by 2ez4gcx, #2756). An inverted clip's filter now gets an extension dictionary with the ACAD_XREC_ROUNDTRIP XRECORD (ACAD_INVERTEDCLIP_ROUNDTRIP, then ..._COMPARE). Reading takes the ROUNDTRIP list as the boundary while COMPARE matches the filter's vertices, so AutoCAD's keyhole filters read as the clip drawn; 290 is still read when present. The record survives DWG, so CADCraft's own CADCRAFT_XCLIP flag is gone.
