  D3D11: Fix basic ReadPixels from 3D attachments.
  
  Use the TextureHelper class to abstractly handle 2D and 3d textures.
  
  Also refactor the Image11 copy methods to be a bit cleaner and not
  use the copy conversion path when unnecessary.
  
  This patch does not yet fix layer attachments - the fix for that will
  come up in a subsequent patch.
