研究方向

Investigate the current toolbar icon implementation for snapping pivot to selection transforms. The snapping logic likely exists for other elements. Look for existing snapping functions and how they are applied. Check the transform system in the codebase, particularly files related to pivot placement and selection transforms. Examine any linked documentation or comments. The implementation might involve adding a snapping check when manually dragging the pivot, triggering alignment to boundary points, midpoints, and corners of the selection bounding box.
