* This allows libEGL to get the function pointer via dlsym, since it can't
* directly link against libgui. In a future release, we'll fix this so that
* libgui does not depend on graphics API libraries, and libEGL can link
* against it. The current dependencies from libgui -> libEGL are:
* - the GLConsumer class, which should be moved to its own library
* - the EGLsyncKHR synchronization in BufferQueue, which is deprecated and
* will be removed soon.
