+ *
+ *
+ * - remove the SG_GLxxxx_H #defines, since OSG provides its own versions
+ * - this exposed a bizarre issue on Mac where dragging in <AGL/agl.h> in
+ * extensions.hxx was pulling in all of Carbon to the global namespace
+ * - very scary. As a result, I now need to explicitly include CoreFoundation
+ * in fg_init.cxx.
+ * - change SG_USING_STD(x) to using std::x
+ *
+ * Issues:
+ *
+ * - the logic for X11 and Win32 in RenderTexture and extensions is tortured,
+ * please see if you agree I got all the ifdefs correct.
