Objects​

Canvas
  size: Vector2I
  testPattern: bool

VideoOutputDevice (Window)
  shows intersection of canvas with its screen rect
  vsync / background from show prefs

VideoTargetLayer
  id, name, rect, locked
  hosts TextureRect (video) and/or text controls

Draw path​

  1. Decoder presents a frame into a texture.
  2. VideoComponent.ApplyTextureLayout sets expand/stretch on the layer’s TextureRect.
  3. When expand is IgnoreSize, the rect fills the layer host.
  4. Each output window composites the canvas region it owns.

OSC / control mutation​

/Layer/{id}/pos and /size (and control Translate layer) mutate layer geometry if unlocked. Locked layers reject OSC moves.

Restore / undo​

Displays settings restore runs DisplaysManager.LoadFromData, recreating windows. UI must rebuild by id after settings history restore.
