Fixes for conformance testing and non-output layers.

  • Value of PicOutputFlag of non-output layers was not being computed correctly. Fixed under MACRO FIX_NON_OUTPUT_LAYER
  • Some fixes for conformance testing under macro FIX_CONF_MODE.

From: Adarsh K. Ramasubramonian <aramasub@…>
  • Property svn:eol-style set to native
