nan 938d95db0f Add new functionality for image rectification and depth metadata handling
- 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.

ADDED Requirements

Requirement: Mask exposes Set Extend and Subtract

Mask MUST 按顺序提供 SET / Set、EXTEND / Extend、SUBTRACT / Subtract,枚举数值分别为 0、1、2;界面和状态文本 MUST 使用 Extend。

Scenario: User extends Alpha

  • WHEN 用户以 Extend 提交值为 mask 的选区到现有 alpha
  • THEN 结果 Alpha 为 max(alpha, mask),RGB 保持不变

Scenario: User uses Set or Subtract

  • WHEN 用户使用 Set 或 Subtract
  • THEN 结果 Alpha 分别为 alpha * mask 或 alpha * (1-mask),RGB 保持不变

Requirement: Mask defaults to Set

Scene 的 Mask Mode 和 Mask Operator 的模式属性 MUST 默认 Set,并通过同一属性定义保持一致。

Scenario: New scene and operator defaults

  • WHEN 创建新 Scene 或未指定模式的 Mask Operator
  • THEN 模式默认值为 SET

Scenario: User chooses another mode

  • WHEN 用户主动设置 Extend 或 Subtract 后启动 Mask
  • THEN 本次操作使用用户保存的模式
