Type-Safe Coordinate System

A comprehensive refactor to prevent coordinate space confusion at compile time.

New Features

  • Typed Coordinate Types - New types in FlowGraph.Core.Coordinates:

    • CanvasPoint, CanvasVector, CanvasRect - Canvas/graph space coordinates
    • ViewportPoint, ViewportVector, ViewportRect - Screen/viewport space coordinates
    • These prevent accidental mixing of coordinate spaces at compile time

  • Type-Safe FlowCanvas API:

    • GetTypedCanvasPosition(e) → Returns CanvasPoint
    • GetTypedViewportPosition(e) → Returns ViewportPoint
    • Use these for extension/Pro code that needs pointer coordinates

  • Mode-Agnostic Input System - All input states now work correctly in both Visual Tree and Direct Rendering modes without special-case handling

Deprecated APIs

The following methods are deprecated and will be removed in a future version:

  • FlowCanvas.GetCanvasPosition(e) → Use GetTypedCanvasPosition(e)
  • FlowCanvas.GetViewportPosition(e) → Use GetTypedViewportPosition(e)
  • ViewportState.ScreenToCanvas() → Use ViewportState.ViewportToCanvas()
  • ViewportState.CanvasToScreen() → Use ViewportState.CanvasToViewport()

Internal Improvements

  • All input states (DraggingState, ConnectingState, BoxSelectingState, etc.) migrated to typed coordinate system
  • IInputCoordinates interface abstracts rendering-mode-specific coordinate conversion
  • IRenderTarget interface provides mode-agnostic temporary visual rendering
  • Removed debug statements from production code
