- Unified the canonical local frame for generated geometries (Plane, Depth Plane, Relief Plane, Cutout, Depth Cutout) to align with Blender's object coordinate system, setting X as horizontal, Z as up, and +Y as depth. - Removed the `Depth Axis` parameter from `O Image Cutout` and `O Image Depth Cutout`, simplifying the geometry generation process. - Updated the depth direction defaults to use +Y instead of -Z for `O Image Relief Plane` and Depth Symmetry. - Adjusted the geometry nodes to ensure thickness, projection, and shell displacements operate along the Y-axis. - Implemented new capabilities for handling object space normals to align with the new canonical frame. - Enhanced the Depth Symmetry functionality to mirror across the canonical Y-axis and perform a final rotation to maintain the correct orientation. - Added tests to validate the new coordinate system and ensure compatibility with existing assets.
