title: WPF BooleanToVisibilityConverter that converts to Hidden instead of Collapsed when false?
body: <p>Is there a way to use the existing WPF BooleanToVisibilityConverter converter but have False values convert to Hidden instead of the default Collapsed, or should I just write my own?  I'm on a project where it's tremendous overhead to do something simple like this (shared stuff goes into a separate solution, and the rebuild/checkin/merge process is an overgrown mutated behemoth of a process), so I'd prefer if I could just pass a parameter to the existing one than to jump through the hoops just mentioned.</p>
