From cd2de115c6216ad747cf4803e65a4ce4af220795 Mon Sep 17 00:00:00 2001 From: Liang Qi Date: Mon, 12 Dec 2016 15:42:24 +0100 Subject: Bundled libtiff updated to version 4.0.7 This commit imports libtiff 4.0.7, including COPYRIGHT, ChangeLog, README, README.vms, RELEASE-DATE, TODO, VERSION and libtiff, port directories. In libtiff, only includes SConstruct, libtiff.def, libtiff.map, libtiffxx.map, tif_config.h-vms, header and source files. In port, only includes header and source files. Upstream changes since 4.0.6 have been merged in, includes 701ba023 and 52dd6b1e. Also updated version in qt_attribution.json.
