/**
 * IntersectionSplitter is a 2D drag handle that appears at the intersection of
 * two perpendicular splitters (e.g., where a horizontal splitter crosses a vertical splitter).
 *
 * This allows users to drag in both X and Y dimensions simultaneously to resize both
 * rows and columns at the same time, similar to VS Code's window management.
 *
 * Key differences from standard Splitter:
 * - Supports 2D mouse movement (both X and Y offsets)
 * - Uses a `move` (4-way) cursor
 * - Positioned at the intersection point
 * - Emits drag events with both offsetX and offsetY
