title: (DirectX9) sRGB conversion after blending
body: <p>I recently came across this blog post <a href="http://altdevblogaday.org/2011/06/02/yet-another-post-about-gamma-correction/" rel="nofollow">Yet another post about gamma correction</a> which taught me the availability of the <a href="http://msdn.microsoft.com/en-us/library/bb172583%28v=vs.85%29.aspx" rel="nofollow">D3DPMISCCAPS_POSTBLENDSRGBCONVERT</a> capability flag.</p>
  
  <p>This should allow for proper sRGB conversion after blending on DirectX9.</p>
  
  <p>What I don't understand is what to do with it? I can query my device Direct3D 9Ex device for this capability but how do I enable it if supported? Do I have the choice between pre and post blending conversion? If yes, how?</p>
  
  <p>Thanks for you help!</p>
