title: Custom shaped Border in WPF
body: <p>I am trying to create a TabControl which matches the style of an existing tab control I use in WinForms, and one of the features of that is that it has tab button shapes like those found in VS (slant on the left, other edges square).</p>
  
  <p>I am just starting out in WPF, so maybe I'm barking up the wrong tree, but I figured I needed to get a Border, and attach it to a Path, so that I could specify some geometry for the border... However, I just can't find any useful information. I found a 'FreeFormContentControl' class on S/O, but that is for masking content to a specific shape, rather than drawing a border around it in a specific shape.</p>
  
  <p>If somebody could point me in the right direction I'd be very much obliged!</p>
