Change Proposal Name OpenCV 4.2.x
Summary
Update OpenCV to 4.2.x. This version drop support for legacy OpenCV version 1 (C style) API over the OpenCV version 2 (C++ style) API. Despite the change was more than 7 years ago, some application keep using the C style API as compatibility was kept up to OpenCV 3.x. The main advantage of OpenCV 4 is a modern Computer Vision Framework advertising: - C++11 compliant - New module G-API for graph-based image procesing pipelines. - Better implementation of few algorithms. - See also https://opencv.org/opencv-4-0/

Detailed Description
Few packages will need to be ported to work with OpenCV 4.2.x
Benefit to Fedora
Scope
- Proposal owners:
Update OpenCV to version 4.2.x and rebuilt few applications that depends on it.
- Other developers: N/A (not a System Wide Change)
- Release engineering: #Releng issue number (a check of an impact with Release Engineering is needed)
- Policies and guidelines: N/A (not a System Wide Change)
- Trademark approval: N/A (not needed for this Change)

Contingency Plan
If few applications are missing support for OpenCV 4.x they will be built with OpenCV support disabled if such support is optional. Application where upstream is already in-active are unlikely to be worked on in the scope of this proposal.
