- Implemented `image_plane.py` to build the Image Plane Geometry Nodes group with customizable parameters for geometry, subdivide, and thickness. - Created `image_plane_validation.py` to validate the functionality of the image plane, ensuring correct geometry generation and material assignment. - Developed `material_layers.py` to construct shader node groups for image materials, including depth and normal handling. - Authored `plane_layouts.py` to define node arrangements for image geometry assets. - Introduced `shadeless.py` to create a shadeless shader node group that displays color without scene lighting while preserving shadows and reflections.

Mask Alpha 编辑
operators/image_edit_tool/mask.py 定义 EditImageAlpha 和 MaskTool，使用 common/viewport.py 的 ImageGesture 管理 Lasso、Brush 与 Polyline。

A[冻结 Scene 的 Gesture、Mode、Radius] --> B[屏幕手势与 Overlay]
B --> C[完成后投影并生成覆盖 M]
C --> D[读取源 RGBA]
D --> E[按模式计算 Alpha]
E --> F[保留 RGB 和源画布尺寸]
F --> G[替换 Packed Image 并提交一个 Undo]
| 模式 | 源 Alpha A 与覆盖 M 的结果 |
|---|---|
| Set | A × M |
| Add | max(A, M) |
| Subtract | A × (1 − M) |
Brush 拖动时维护简化屏幕路径、圆形印记与连接条的并集预览；释放时一次生成图片覆盖。Polyline 使用逐点路径，至少三个点后通过闭合圈、双击或 Enter 完成，Backspace 删除末点。
结果保留 Empty 的身份、矩阵、显示尺寸和偏移。全透明结果有效，取消或切换工具清理未提交的 Overlay；共享 Image 通过统一替换入口分流。
