-/**
- * Helper class for working around problems with open-source DRI
- * drivers. In the current DRI implementation it is required that the
- * symbols in libGL.so.1.2 be globally visible to be accessible from
- * other libraries that are dynamically loaded by the implementation.
- * Applications may typically satisfy this need either by linking
- * against libGL.so on the command line (-lGL) or by dlopen'ing
- * libGL.so.1.2 with the RTLD_GLOBAL flag. The JOGL implementation
- * links against libGL on all platforms rather than forcing all OpenGL
- * entry points to be called through a function pointer. This allows
- * the JOGL library to link directly to core 1.1 OpenGL entry points
- * like glVertex3f, while calling through function pointers for entry
- * points from later OpenGL versions as well as from
- * extensions. However, because libjogl.so (which links against
- * libGL.so) is loaded by the JVM, and because the JVM implicitly uses
- * RTLD_LOCAL in the implementation of System.loadLibrary(), this
- * means via transitivity that the symbols for libGL.so have only
- * RTLD_LOCAL visibility to the rest of the application, so the DRI
- * drivers can not find the symbols required. <P>
- *
- * There are at least two possible solutions. One would be to change
- * the JOGL implementation to call through function pointers uniformly
- * so that it does not need to link against libGL.so. This is
- * possible, but requires changes to GlueGen and also is not really
- * necessary in any other situation than with the DRI drivers. Another
- * solution is to force the first load of libGL.so.1.2 to be done
- * dynamically with RTLD_GLOBAL before libjogl.so is loaded and causes
- * libGL.so.1.2 to be loaded again. The NativeLibrary class in the
- * GlueGen runtime has this property, and we use it to implement this
- * workaround.
