parralax property missing

The documentation states that there is spriteBatch extension method that allows for a parallaxmode to be set.
However, there is no such extension.

Start by locating the documentation that mentions the SpriteBatch extension and parallax mode, then compare that reference with the available C# API. Determine whether the intended result is to add the missing extension or correct the documentation; done means the documented behavior and available API agree.
