* $Log: glu.h,v $
* Revision 1.10 1999/09/19 10:04:01 tjump
* Changed name 'glGetProcAddressEXT' to 'gluGetProcAddressEXT'
*
* Revision 1.8 1999/09/17 12:21:36 brianp
* glGetProcAddressEXT changes to accomodate Win32 and non-Win32
*
* Revision 1.7 1999/09/17 02:44:19 tjump
* I changed the xxxGetProcAddressEXT function declarations to be more
* MSVC friendly. Brianp - could you verify that they describe and operate
* as intended on Linux/ETC platforms?
*
* Revision 1.6 1999/09/16 16:54:22 brianp
* GLU_EXT_get_proc_address clean-up
*
* Revision 1.5 1999/09/14 03:23:08 gareth
* Fixed GLUtriangulatorObj again (spelling).
*
* Revision 1.4 1999/09/14 01:32:58 gareth
* Fixed definition of GLUtriangluatorObj for 1.3 tessellator.
*
* Revision 1.3 1999/09/11 11:34:21 brianp
* added GLU_EXT_get_proc_address
*
* Revision 1.2 1999/09/10 02:08:18 gareth
* Added GLU 1.3 tessellation (except winding rule code).
*
* Revision 1.1.1.1 1999/08/19 00:55:40 jtg
* Imported sources
*
* Revision 3.6 1999/02/14 03:39:45 brianp
* updated for BeOS R4
*
* Revision 3.5 1999/01/03 03:02:55 brianp
* now using GLAPI and GLAPIENTRY keywords, misc Windows changes (Ted Jump)
*
* Revision 3.4 1998/12/01 02:34:27 brianp
* applied Mark Kilgard's patches from November 30, 1998
*
* Revision 3.3 1998/11/17 01:14:02 brianp
* minor changes for OpenStep compilation (pete@ohm.york.ac.uk)
*
* Revision 3.2 1998/07/26 01:36:27 brianp
* changes for Windows compilation per Ted Jump
*
* Revision 3.1 1998/06/23 00:33:08 brianp
* added some WIN32 APIENTRY, CALLBACK stuff (Eric Lassauge)
*
* Revision 3.0 1998/02/20 05:06:01 brianp
