f3adcda6b7 Removed the GLclampd declaration and replaced its usage with GLdouble to standardize the OSG extension setup with current GL/GLES headers. 
Added a float fallback from osg::DepthDangeIndex to suppprt GLES.

89f7726383 Copied libutil and libtess implementations in form Mesa 7.9/src/glu into the src/osg/glu, 
changed extensions from .c to .cpp and got compiling as C files as part of the osg core library.

Updated and cleaned up the rest of the OSG to use the new internal GLU.

528fdbb75c Aded osg::isGLExtensionOrVersionSupported(uint contextID, char* extensionName, float minVersionRequired) method that 
returns true if (the extension string is supported or GL version is greater than or equal to a specified version) and 
non extension disable is used.   This makes it possible to disable extensions that are now
available as parts of the core OpenGL spec.

Updated Texture.cpp is use this method.

fe207a09c1 From Sherman Wilcox, "Minor change to bool setGLExtensionFuncPtr(T& t, const char* str1) and

3333ca2b46 From Mathias Froehlich, "I have extended the X11 pbuffer code to use either the complete set of glx 1.3 
pbuffer functions or exactly ask for the extensions we need to call the
apropriate glx extension functions for and around pbuffers extensions.
The glx 1.3 version of this functios are prefered. If this is not pressent we
are looking for the glx extensions and check for them.
Prevously we just used some mix of the glx 1.3 functions or the extension
functions without making sure that this extension is present.

409cdd0b28 Intoduced a new setGLExtensions template method to do a copy of void* pointer to 
local function pointer to avoid compiler warnings related to case void*.

Moved various OSG classes across to using setGLExtensions instead of getGLExtensions,
and changed them to use typedef declarations in the headers rather than casts in
the .cpp.

Updated wrappers
