Due to an oversight in the code, the fallback code would simply fail to work as the encoder was always the zero-copy version. This resulted in weird crashes and encoders not working that used to work before.
Fixes#295
Proxies allow for older configurations to work fine on newer versions, without having to manually adjust the scene collection to match the new ids at all. Thanks to the migration system we can freely support any number of old versions, as long as we write migration code.
Using std::string_view over std::string (and const std::string&) has the advantage that we skip potential temporary std::string objects that are immediately thrown away, thus slowing down the code. It can also be implicitly cast to std::string, which makes it compatible with existing code that uses std::string.
Adds a new CMake option "ENABLE_PROFILING" which enables all CPU and GPU performance profiling available in StreamFX for tracking what's actually causing things to be slow.
The new libOBS API allows us to directly access the underlying API instead of having to mess around in memory. By using it we can avoid crashing in case the compiler for it is different, or in case the actual back end structure changes.
Additionally the mostly unimplemented and unused options have also been removed, which streamlines the use of this class even further and reduces both shader and code complexity.
Finally by optimizing the use of the internal render target we can achieve a speed up of up to 3000% over the old way, allowing for many more mipmapped filters.
Previously sources had to manually implement migration code, which resulted in unresolvable regression issues due to the lack of version and commit tagging. With the new migration code, all sources automatically have this version and commit tagging at all times, and as such can now have a temporary regression fixed without the user needing to change any values manually.
With this, GCC 8 and above should now be able to compile the project both in obs-studio and as a standalone install. Some features are currently still not fully supported and require extra work, but the majority of things are supported and work out of the box. Exact feature parity can be looked up here on the wiki: https://github.com/Xaymar/obs-StreamFX/wiki/Platform-Feature-Parity

This header includes all common data between headers used in the plugin. This should improve cross-platform compiling support whenever possible, as all platform-dependent common includes and defines can be done here.
The current implementation of obs_properties_remove_by_name corrupts the obs_properties_t object whenever it is called on the first or last property in the list. This leads to rapid unscheduled disassembly, and therefore must be fixed in order for this function to be used.
Fixed by upstream PR https://github.com/obsproject/obs-studio/pull/2257.
