octave: libinterp/dldfcn/__magick_read_

annotate libinterp/dldfcn/__magick_read__.cc @ 16983:4660d047955e

Make use of gripe_disabled_feature() for image IO functions. * __magick_read__.cc: use gripe_disabled_feature() instead of error() to fail due to missing features. Comment code instead of CPP "#if 0". Enclose maybe_initialize_magick() in the more general #ifdef HAVE_MAGICK. It was the only function outside it, instead having a separate condition inside the function causing a warning about empty function in systems without Magick++.
