DragVisual record struct Core

DragVisual

public DragVisual(string Label, double GhostX, double GhostY, double DropLineX, LogRect DropRect, string DropZoneText = "", LogRect SourceRect = default, double ZoneFade = 1);

Transient drag overlay (column reorder / drag-to-group): a floating ghost of the dragged caption at the cursor + a drop indicator. All in VIEWPORT pixels (the host computes them), so the renderer just paints them on top. DragVisual.DropLineX = insertion line x (NaN = none); DragVisual.DropRect = a highlighted drop zone, e.g. the group panel (empty = none).
