+# XPositionReference
+
+XPositionReference is used as a fake horizontal offset indicator.
+
+The truth is that the svg will always take the left for its transformations and the best for us is to do the same.
+
+That's why everything that is shown to the user about XPositionReference is an illusion. Like for example:
+- The inputs, see `PropertiesOperations.ts`, `StaticForm`, `DynamicForm`.
+- Child dimensions, see `Container.ts`.
+
+
+Look for use of `transformX()` and `restoreX()`.
