All ViewHelpers are now documented. Including Fluid's own ViewHelpers.
Improvements for the Fluid ViewHelper argument insight has been greatly improved. Now, all inherited arguments are registered and both arguments registered using $this->registerArgument() and as argument for render() are recognized.
To celebrate this update I've added a section with a complete and exhaustive <link internal-link internal link in current>documentation on all arguments for all the built-in Fluid ViewHelpers such as f:for, f:cObject etc.
Search facetting has also been cleaned up and improved to help search through the many, many pages of documentation.
