Library updates checked into GIT:

  libvpx from 1.13.1 to 1.14.1

  libwebp from 1.3.2 to 1.4.0

That completes the library updates for a while except for libjpeg-turbo which is currently at 2.1.5.1 and could be updated to 3.0.3 but does not build.  Maybe when Andrew has time he can look at this -- I think the error is due to WITH_12BIT, but I do not know for sure or how to fix that.  It seems like the below url thinks it is in CMakeLists.txt.  I did compare it to the current version but there are a lot of  differences.  URL is:  https://github.com/libjpeg-turbo/libjpeg-turbo/issues/466
