Description:	These functions are easy to implement on Windows: `XEqualRegion()`, `XOffsetRegion()`, `XPointInRegion()`, `XUnionRegion()`, `XXorRegion()` These functions are easy to implement on Aqua: `XPointInRegion()`, `XUnionRegion()`, `XXorRegion()` For `XEqualRegion()` on Aqua, macOS does not have a corresponding public API, but a suboptimal implementation is possible using `HIShapeCreateXor()` and `HIShapeIsEmpty()`. The functions `XXorRegion()` and `XEqualRegion()` do not already have reserved stub entries. Here is what I attempted so far (based on core-8-6-branch). For Windows, some implementations match those in TkZinc’s replacement functions.
User Comments:	jan.nijtmans added on 2025-10-31 11:07:59: Fixed [481aff8c2bc48eb3\|here] Thanks for the report and your patch (based on 8.6). I used it as base for the Tk 9.1 fix. Since we generally don't add new stub entries in a minor release, it will only be available for Tk 9.1+ jan.nijtmans added on 2025-09-30 16:23:02: How about this?
