nan 591e62085a feat(cutout): implement boundary padding for cutout textures
- Introduced a new `Boundary Padding` preference in the Cutout Tool with a default of 2 px and a configurable range of 1-4 px.
- Updated the Cutout client to establish inward mapping from the final Mask, sampling in a fixed direction and processing independent material RGBA and Depth.
- Enhanced the handling of RGBA and Depth during cutout operations, ensuring proper mapping and preservation of source data.
- Added tests to validate the new boundary padding functionality and its integration with existing cutout processes.

feat(geometry): remove overall mesh smoothing from geometry nodes

- Removed the `Smooth` input from several geometry node groups to eliminate unnecessary overall mesh smoothing.
- Retained `Smooth Weight` for depth nodes while removing it from Cutout and Relief Plane nodes.
- Ensured that boundary, normal, and fill smoothing behaviors remain intact and consistent.
- Updated tests and documentation to reflect the changes in node interfaces and behaviors.

feat(normals): scale tangent normals with depth

- Reused the existing `o_normal_reduction` attribute to adjust Tangent Normal strength based on the geometry's `Depth Scale`.
- Ensured that Tangent Normal strength is consistent with the geometry depth, preserving full strength for materials that do not provide the attribute.
- Updated tests to verify the correct behavior of normal strength adjustments in both Tangent and Object Space.

1. Relief depth behavior

  • 1.1 Add the public Depth Offset distance input to O Image Relief Plane, with a default of one and signed range; expose Depth Direction, Depth Offset, and Depth Scale directly below Thickness in that order.
  • 1.2 Add Depth Offset to Reference Depth before reference_plane_depth(), then replace the thickness-dependent inward limit with a zero clamp after direction adjustment and Depth Scale, preserving fixed-base and side-layer weighting.

2. Behavior verification

  • 2.1 Update Relief Plane geometry tests to verify far depths stop at Thickness, positive depths remain unrestricted, and the fixed base and side interpolation remain valid.
  • 2.2 Add positive, negative, and zero Depth Offset tests, including direction adjustment, Depth Scale = 0, and checks that Depth Offset is scaled as part of the corrected relative depth while the depth-zero height remains fixed.
  • 2.3 Update the node-group interface inventory test for Depth Direction and Depth Offset names, order, panel placement, and old base-plane clamp behavior.

3. Node asset

  • 3.1 Run uv run node-group build to rebuild and validate src/anyimage/assets/O_AnyImage.blend from the updated source and tests.
  • 3.2 Run the relevant Relief Plane and plane-object tests, then inspect the final diff for stale inward-limit nodes or old behavior references.

4. Initial depth direction

  • 4.1 Extract the robust plane-direction fit into common.depth and reuse it from Cutout Symmetry calibration.
  • 4.2 Fit the complete valid Relief depth image in local plane coordinates and initialize the new Modifier's Depth Direction.
  • 4.3 Add sloped-depth initialization and shared calibration regression tests.
