  Do not apply UNPACK_SKIP_IMAGES for 2D textures on D3D
  
  Resubmitted with test skip added for Intel OpenGL.
  
  GLES 3.0.4 section 3.8.3:
  
  "For the purposes of decoding the texture image, TexImage2D is
  equivalent to calling TexImage3D with corresponding arguments and
  depth of 1, except that UNPACK_SKIP_IMAGES is ignored."
  
  An "applySkipImages" boolean parameter is added to the functions in
  the D3D backend that apply skip offset to the unpack pointer. In case
  2D texture data is uploaded, the parameter is set to false and
  UNPACK_SKIP_IMAGES is not applied.
