* restore regular form, set color info for shape header
*
* Revision 1.6 2003/11/25 15:47:56 warmerda
* Added surface type for complex headers: Marius
*
* Revision 1.5 2003/11/04 14:23:46 warmerda
* added check after create
*
* Revision 1.4 2003/05/15 14:47:24 warmerda
* implement quaternion support on write
*
* Revision 1.3 2003/05/12 18:48:57 warmerda
* added preliminary 3D write support
*
* Revision 1.2 2003/01/20 20:05:07 warmerda
* added cell header test, and make c clean for windows build
