Subject: [PATCH] Load libEGL and libGLES2 symbols implicitly
Instead of explicitly loading libraries from hard-coded locations,
we now just call dlopen(NULL, RTLD_LAZY). This returns a handle to
the host process'es context, which already contains the symbols of
both these libraries, because we link against them.
It was necessary to bypass LoadLibrary, because that expects a non-NULL
file path, so we couldn't pass NULL through that interface.
