- Use auto in places where code clarity is improved or identical.
- Replace trivial constructors and destructors with default.
- Use true random for random generation.
- Use std::string_view where it is valid to do so.
- Apply const where it is valid to do so.
- Use references where it is valid to do so.
- Manually optimize memory usage with std::move and std::copy.
- Opt for memory efficient containers where the size is known ahead of time.

As the recursion checking code is somewhat broken in libOBS, we need something to prevent accidental recursion from occurring. While the alternative fix is to simply make all of libOBS support recursion, unfortunately that endeavor would be too large for a single person to take on.
In some rare cases, a bug is observed where some sources end up missing despite being visible in the OBS Studio UI. This is most likely related to us actually missing the events due to plugin load order. We can fix this by explicitly enumerating sources in the constructor.
Additionally in order to reduce the human error factor, we should avoid explicit initialize() and finalize() calls for our singleton. Instead the get() function should do all of the heavy lifting, including thread safety, so that the human writing the code will have next to no chances to break it.
Improves cross-platform compatibility of Shaders written for StreamFX through the use of preprocessing to make things a bit more compatible. While we don't perform any proper parsing, this will be able to prevent basic issues.
As not all encoders need all functions, classes inheriting from this should not need to implement all of them as no-ops. Instead the header should take care of this, which reduces duplicated empty code paths.
Changes applied:
* Moved utility files to /util/.
* Removed unused #includes.
* Removed unused ::ffmpeg::tools function.
* Removed unused variables.
* Fixed missing parentheses in the version macro.
* Fixed missing override on virtual function overrides and removed unnecessary virtual keyword from them.
* Disabled additional warning for ATL headers on MSVC only.
* Replaced direct printf parameters with their macro equivalent.
* Replaced C-style casts with C++-style casts.
* Applied clang-format again after an earlier change to the CMake file broke the integration for it.
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.
