nan 31074bd511 Add tests and implement boundary smoothing and cutout functionality
- Introduced tests for boundary smoothing in `test_boundary_smoothing.py`, verifying that smoothing reduces stair-step artifacts while preserving boundary integrity.
- Added tests for cutout boundary behavior in `test_cutout_boundary.py`, ensuring proper handling of boundary triangles and normal blending.
- Created `test_temporary_attributes.py` to check the cleanup of temporary attributes across depth modifier branches, ensuring no warnings are raised.
- Implemented point culling functionality in `test_validity.py`, confirming that invalid points are removed without affecting adjacent geometry.
- Developed boundary smoothing logic in `boundary_smoothing.py`, allowing for depth smoothing while maintaining edge integrity.
- Added cutout boundary management in `cutout_boundary.py`, including functions for removing boundary triangles and tapering thickness profiles.
- Implemented validity checks in `validity.py` to ensure proper deletion of invalid vertices and associated wire edges.

Why

Texture Paint 模式粘贴图片后,笔刷已使用该图片作为纹理,但图标仍显示原有预览,难以直接识别绘制内容。将笔刷图标同步为粘贴图片,让选择笔刷时的视觉提示与实际纹理一致。

What Changes

  • Texture Paint 模式绑定粘贴图片后,同步更新当前可编辑笔刷的自定义预览。
  • 预览保持图片比例,支持已打包的剪贴板图片及重复粘贴更新。
  • 验证预览即时刷新,以及保存并重新打开文件后的保留效果。

Capabilities

New Capabilities

  • pasted-brush-preview: Texture Paint 粘贴图片与笔刷预览同步。

Modified Capabilities

Impact

  • src/anyimage/operators/clipboard_image/actions.py:笔刷纹理绑定与预览更新。
  • src/anyimage/common/image.py:复用现有图片读取或导出能力。
  • tests/anyimage/operators/test_clipboard_image.py:增加预览行为覆盖。
  • 使用 Blender 自定义预览 API,沿用现有依赖。
