Update openexr to 3.1.3

Authored by YakoYakoYokuYoku on Oct 27 2021, 2:29 PM.




  • 3.1.3:
    • Default zip compression level is now 4 (instead of 6), which in the test suite improves compression times by 2x with only a tiny drop in compression ratio.
    • Both setDefaultZipCompression() and setDefaultDwaCompression() now set default compression levels for writing.
    • The Header now has zipCompressionLevel() and dwaCompressionLevel() to get/set the levels used for writing.
  • 3.1.2:
    • Proper handling of pthread with glibc 2.34+.
    • Miscellaneous fixes for handling of invalid input by the new OpenEXRCore library.
