2018-07-03Avoid duplicate data buffering in CPDF_SyntaxParser::ReadStream().Artem Strygin
Allow sub-streams created from an IFX_SeekableReadStream to provide stream data without copying memory. The data will only reside in the top-level stream. For example: For file http://www.major-landrover.ru/upload/attachments/f/9/f96aab07dab04ae89c8a509ec1ef2b31.pdf (18 Mb) The memory usage is reduced by ~13 Mb.
