image/jpeg: send a correct Start Of Scan (SOS) header. Section B.2.3 of http://www.w3.org/Graphics/JPEG/itu-t81.pdf discusses the End of spectral selection (Se) byte. Apparently many JPEG decoders ignore the Se byte (or let it through with a warning), but some configurations reject them. For example, http://download.blender.org/source/chest/blender_2.03_tree/jpeg/jcmaster.c has these lines: if (Ss != 0 || Se != DCTSIZE2-1 || Ah != 0 || Al != 0) ERREXIT1(cinfo, JERR_BAD_PROG_SCRIPT, scanno); Fixes #3916.
