title: Stencil buffer depth in OpenTK
body: <p>I`m using OpenTK for OpenGL and C#.</p>
  
  <p>I need to use stencil buffer and currently wondering how do I set <code>StencilBuffer</code> depth.</p>
  
  <p>As I know earlier was TaoFramework and it`s control had property where this depth could be seted.</p>
  
  <p>But now in openGlControl from OpenTK I can not find such property. As I know current seted buffer depth can be obtained by calling <code>GL.GetInteger()</code> method passing to it special parameter.
  And when I do so it returns 0. This means that currently stencil buffer depth is zero, so any operations won"t have result untill some buffer depth is seted. But I can`t find out how to do this.</p>
  
  <p>Can anyone help me?</p>
