The SelectionManager class acts as the "Brain" of the selection system.
It is responsible for:
- Storing the "Truth" of the selection:
- The original shape (mOriginalRect)
- The current transformation state (mSelectionTransform) including position, rotation, and scale.
- Performing the Math:
- Calculates new transformations based on user input from the SelectTool.
- Handles complex matrix operations for rotation and scaling.
- Coordinate Space Management:
- Converts points between "Screen Space" (mouse coordinates) and "Selection Space" (drawing coordinates).
- Maps operations from the UI (SelectTool) to the underlying data.
The SelectTool (the "Hand") delegates all state tracking and heavy calculation to this manager.
