- Also removed "crop" from Clip class, as it was never implmeneted correctly, and we have a fully functional "crop" effect when needed
- Added caching to Clip class, to optimize previewing of cached frames (much faster than previous)
- Replacement method names are SetParentClip/GetParentClip
- Old names are retained as deprecated alternates, for now
- libopenshot internal calls (very few) are updated
ReaderBase.cpp: Remove (Set,Get)Clip
- Parsing from string to Json::Value is now done by utility function
openshot::stringToJson() in Json.cpp, all SetJson() methods call it.
- Expand use of const member functions and args where appropriate.
- Use std::to_string() to format int/float values as strings.
- Correct mentions of nonexistent Json::JsonValue type in docstrings
It turns out SWIG is a lot pickier than GCC about namespaces, and
requires a lot more `openshot::` prefixing in our headers, if we
eliminate the `using namespace...` statements from them.
* Integration of libresvg SVG library (optional during build)
* Major refactor of max_width and max_height for preview optimization
* Fixed many bugs related to preview resizing, with regards to cached frames
* Updating gitlab CI to find RESVGDIR correctly for windows, and adding svgz support
* Updating cmake findresvg module to search for windows locations first, to prevent an issue on our windows builders and updating some CMake output.
* Removing folder path from resvg header, since it could be installed in different named folders. This is an attempt to fix Windows include issues.
* Making call to AV_FREE_FRAME conditional for non windows systems (because it crashes on Windows for seemingly no reason). Needs more investigation.
Also, much work has been done on memory management / leak detection, and optimizations with multi-threading... including a new thread cacher class used by the video playback (which is smoother than ever).
