Rendering will now use a cached version of the mirrored source in order to reduce rendering cost drastically for heavy sources or scenes. Additionally rescaling now uses the internal scene instead of being a custom implementation, allowing for some new things.
Rescaling now has a new option: Bounds Type! This option allows control over just how a source is scaled, by default it is set to Stretch, but there are other options that can keep the aspect ratio of the mirrored source in tact.
Additionally the ScalingMethod struct has been replaced with obs_scale_type, which means that Bilinear Low Resolution is now no longer an option.
Implements #35
Initialization happens in the constructor again, as using a delayed initialization only caused update() to be slower.
Additionally refactored some variable names to make more sense.
load() is guaranteed to happen after all sources have been created and no earlier, and we can use update() to guarantee that we don't need to duplicate our initialization code in case we go back to initializing earlier than load().
This fixes the multi-reference issue that caused Source Mirror to keep a permanent reference to a source that should have been released.
The obs::audio_capture was also updated to now use the util::event code for improved callback support. There are a bunch of new additional checks in the acquire_input function that prevent bad references from happening, and is also now self-cleaning through the use of obs::source
While Linux was not an original goal of the project, it should still be supported out of the box. Therefore a number of changes are contained in this changeset:
- All C++ .h files were renamed to .hpp.
- All C includes (<....h>) were replaced with C++ includes (<c...>) and missing includes were added.
- std::memset and std::memcpy was replaced with memset and memcpy.
- All anonymous structs were removed where necessary.
- `extern "C"` was removed where it wasn't needed.
- #pragma warning was placed behind an #ifdef _MSC_VER
- The macros for `min`, `max` and `clamp` were removed as they were not used.
- `-fpedantic` was added to the GCC flags for bitmask support.
- `gs::rendertarget_op` is now declared before use.
- std::exception(const char*) was replaced with std::runtime_error(const char*).
- Added aligned_alloc and aligned_free macros for GCC and MSVC support.
- Replaced use of `sprintf_s` with `snprintf`.
- Placed additional guards around windows only code.
Additonally some changes were made that do not affect Linux:
- `NOMINMAX` and `NOINOUT` were removed.

Due to the lack of checking aud and aoi, a rare race condition crash can be observed with audio mirroring enabled on closing OBS. In this case, aoi is used even though it is null, causing OBS to crash instead of closing normally.
Fixes#22
From this point on, Source Mirror is now capable of real-time mirroring of Video and Audio. This can help if you need different filters per scene for your microphone or voice chat, depending on the scene (audio ducking for pause scene, no audio ducking for live gaming).
Scaling was previously incorrectly rendering the source with another effect forced onto it, resulting in slower rendering and some sources that would no longer render properly.
Additionally the new option allows the user to have the source render at the original resolution in order to allow previously applied transform to stay identical. The rescaling however will no longer apply to filters after this source then, thus the speed bonus is lost.
Also categorized the localization file and adds descriptions for existing and new properties for Source Mirror.
The source allows you to apply effects to the same source without requiring a new instance of the source. Any changes done to the original source also apply to the mirror, so there is less total work that needs to be done.
It can also rescale the source, allowing you to use the same source as a cheap instant backdrop with Blur for example. What you do in the end is completely unwritten and up to you to decide.
