The Tor software protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, it prevents the sites you visit from learning your physical location, and it lets you access sites which are blocked. @ text @d1 1 a1 1 $NetBSD: patch-image_decoders_nsJPEGDecoder.cpp,v 1.1 2015/07/09 14:13:52 ryoon Exp $ d3 1 a3 1 --- image/decoders/nsJPEGDecoder.cpp.orig 2015-05-04 00:43:19.000000000 +0000 d53 1 a53 1 @@@@ -450,6 +469,15 @@@@ nsJPEGDecoder::WriteInternal(const char* d66 1 a66 1 d69 2 a70 1 @@@@ -632,7 +660,11 @@@@ nsJPEGDecoder::OutputScanlines(bool* sus d82 2 a83 1 @@@@ -959,6 +991,282 @@@@ term_source (j_decompress_ptr jd) a85 1 @
