Ugh it's not this simple...needs extents too. We should just call tuples and normalize everything when pushing to the array. |
Extend CRS handling from intersection to union and difference operations. Use `mutual_crs` to preserve coordinate reference system information when creating result polygons in non-crossing cases, hole handling, and multipolygon operations. Fixes type mismatches when clipping geometries with different CRS configurations.

…g conversion Implements trait-based dispatch in `_linearring` helper to convert LineString geometries (e.g., from ArchGDAL) to LinearRing while preserving CRS metadata. This ensures compatibility with all GeoInterface-compatible geometry types. The function uses trait dispatch pattern: - Returns LinearRing geometries as-is - Converts LineString to LinearRing with CRS preservation - Includes concrete type specializations for GI wrappers (optimization) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
Adds missing CRS parameter propagation in `intersection.jl` to match the pattern already used in union and difference operations. This fixes type conversion errors when using ArchGDAL geometries in intersection operations. Changes: - Pass `crs` parameter to `_trace_polynodes()` call (line 87) - Wrap `tuples()` results with `_linearring()` in non-crossing cases (lines 91, 93) With this fix, all 72 intersection and union operations now succeed across GeoInterface, ArchGDAL, and LibGEOS geometry combinations. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>

Address review feedback: put isnothing checks first since the compiler will optimize them away, making the equality check right above the error more clear. Also cache GI.crs calls and update docstring. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <[email protected]>

Finally, this propagates CRS through polygon clipping.
