compiz opengl plugin leaks a dlopen handle to itself

[Daniel van Vugt]

Compiz opengl plugin leaks a handle to itself (libopengl.so). This means that if plugins are reloaded, the old copy of libopengl.so stays in memory.

Really instead of:
            dlhand = dlopen ("libopengl.so", RTLD_LAZY);
            funcPtr = (GL::FuncPtr) dlsym (dlhand, name);

it should be more like:
            funcPtr = (GL::FuncPtr) dlsym (RTLD_DEFAULT, name);
