    Bug 783203 - Transform ops are opting out of multi-threading
    
    After the last commit, multithreaded transform ops are faster than
    single threaded, so reenable multithreading.
    
    Note that this doesn't necessarily mean that the transform ops are
    faster when using GEGL_THREADS>1, rather than GEGL_THREADS=1,
    only that *when* GEGL_THREADS>1, the multithreaded version is
    faster than the single threaded one.  However, GEGL_THREADS>1 seems
    to be consistently faster than GEGL_THREADS=1 when using a non-
    nearest sampler.
    
    This reverts commit b54454fd225c5a807b680dc1be14cba62acfafd7.
