   Issue with 3D texture
  Hi all,i use a 3D texture as render target in my application.and i draw some textures to it. but the image is distorted if the 3D texture width or height is set to odd number.i need your help.   
  Make sure the width and height are the same as the viewport.  Also, check to see if there are issues with non-power-of-two sized textures.
