title: Changing the cursor appearance in Visual Studio Code via extension API
body: <p>Is it possible to change the cursor appearance in Visual Studio Code using the extensions API?  Knowing that VS Code is built on top of Chromium, and that there isn't a way to style the text cursor in a browser using CSS, it wouldn't seem likely.</p>
  
  <p>I'm messing around and trying to implement some simple modal editing, and I would like to create a block cursor like vim in normal mode.</p>
