Letu Ren	0de26fd78e	Add zlib-ng as an alternative zlib implementation ... Zlib-ng is zlib replacement with optimizations for "next generation" systems. Its optimization may benifits image library decode and encode speed such as libpng. In our tests, if using zlib-ng and libpng combination on a x86_64 machine with AVX2, the time of `imdecode` amd `imencode` will drop 20% approximately. This patch enables zlib-ng's optimization if `CV_DISABLE_OPTIMIZATION` is OFF. Since Zlib-ng can dispatch intrinsics on the fly, port work is much easier.

Letu Ren	baf07f9a03	Update 3rdparty zlib to 1.3 ... The opencv zlib patch is still not merged. So I applied it to zlib-1.3. Since zlib-1.3 didn't modify CMakeLists.txt, opencv's zlib CMakeLists.txt doesn't need to be modified.	12 months ago
Alexander Alekhin	1b1bbe4262	Merge pull request #22801 from alalek:update_zlib ... * 3rdparty: zlib 1.2.12 => 1.2.13 https://github.com/madler/zlib/releases/tag/v1.2.13 - replace README -> LICENSE in install distribution * 3rdparty(zlib): re-apply patch 20190330-ununitialized-use-state-check.diff	2 years ago
Vadim Pisarevsky	f78a3b4cc1	updated 3rd party libs: CLapack 3.1.1.1 => 3.2.1, zlib 1.2.3 => 1.2.5, libpng 1.2.x => 1.4.3, libtiff 3.7.x => 3.9.4. fixed many 64-bit related VS2010 warnings	15 years ago
