- Implemented a preview tool for rectifying images with interactive aspect controls in `preview.py`. - Added tests for depth metadata loading to ensure consistent schema usage in `test_depth_metadata.py`. - Developed comprehensive tests for cutout calibration processes in `test_cutout_calibration.py`, including stability checks and depth calibration. - Created tests for frame compositing operations in `test_frame_compositing.py`, ensuring correct handling of depth and transparency. - Introduced material slot inheritance functionality in `material_slots.py` to manage geometry material assignments. - Built shared shader nodes for material processing in `shader.py`, including roughness and bump mapping setups.

Rectify 透视校正
operators/rectify_tool/operators.py 定义 RectifyImagePerspective 与 RectifyTool，将图片内的四角区域校正为矩形。geometry.py 负责四角验证与像素校正，preview.py 负责预览图、Overlay 和宽高比控制，__init__.py 导出类型及注册清单。
flowchart TD
A[点选四角] --> B[规范为凸 Quad 并检查图片交叠]
B --> C[512×512 预览与宽高比调整]
C --> D[按像素密度和输出上限确定尺寸]
D --> E[分块 Homography 与预乘 Alpha 插值]
E --> F[按可见 Alpha 裁剪]
F --> G[映射 placement bounds 并替换 Packed Image]
四角允许任意点击顺序，退化或非凸输入在提交前校验。预览根据源颜色空间配置显示，像素重采样复用 common/image.py。输出最长边上限 8192，总像素上限 16,777,216。
replace_empty_image() 根据校正区域的 placement bounds 调整画框，保留源 Image 名称、对象身份和共享引用语义。
