c1b3972550 gfx/shader/param/basic: Fix bool and suffixes, add enums and optimize
Adds support for enumerations, a different way of selecting how something should behave in a shader. Enumerations rely on a continuous list of values, and will automatically detect how many values there are in the enumeration. Only non-vector types are supported as enumeration entries, and array/vector parameters can have each member set to a different enumeration value.

Furthermore suffixes now are properly assigned, and 'bool' no longer causes shaders to stop rendering. Additionally by inlining some functions and using std::string_view we can achieve a slightly better performance than before.

fb024cad73 gfx-blur-dual-filtering: Implement asynchronous rendering
Asynchronous rendering allows the GPU to perform work while the CPU performs other work, and is significantly faster than lockstep immediate rendering. By reusing existing render targets we can see a performance improvement of up to 500%, while still doing the same things.

5291b193e2 gfx-shader: Fix rendering at unexpected sizes and fix performance
Fixes rendering at unexpected sizes by first rendering to a render target and then rendering the contents of that render target to the frame buffer instead. This also prevent rendering twice or more, which might cause severe FPS impact.

9ca190c96a gfx-shader: Don't use modified_properties to reload shaders
As OBS Studio locks some mutexes in a different order depending on what actions are being done, using modified_properties for GPU work causes things to freeze in place. Instead have users manually click the refresh button when they changed files in order to prevent this freeze from happening.

cc9d3486b2 project: Fix Linux support by fixing errors and warnings
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

79406b0b08 gfx-shader: Additional stable time values
'Time.x' gets inaccurate if OBS Studio is running for more than two hours, therefore we have to do something to fix it. By allowing the shader code to control when things loop using 'Time.y' (0..1) and 'Time.z' (the number of times 'Time.y' wrapped back to 0), a much more stable animation can be achieved.

6ae9904e13 gfx-shader: Support for filters and transitions
Due to render logic required for transitions, some of the render logic is split into an additional function called 'prepare_render'. Additionally the storage for some temporary objects has been removed as it these objects usually do not outlive their rendering time anyway.

Scaling is now fully supported for Floats and Integers, which allows much higher precision inputs, or upscaling to a different range. Complex functions for scaling are not supported as those would be a scripting thing and should be kept as that (OBS Studio has built in Lua scripting).

Additionally, enumerations are now correctly loaded with data.

777556f4f6 gfx-shader-param: Vastly improve parameter functionality
Allow for overriding type and size of an element, opening the path for `int#[]`, `float#[]`, `int#x#`, `float#x#`, `bool#x#`, `vector<type, #>` and `matrix<type, #, #>`. Also allows for specifying the exact type of texture instead of hoping the user gets it right, as well as samplers.

Parameters are also now created if they are invisible, which means that the properties() function must not be called, but they must still be used like any other. This is due to a problem with default values not being applied all the time, and sometimes just vanishing.

The code also now throws exceptions with reasonable text, which should be caught by the gfx::shader implementation and refuse a load of the effect. No other state should be modified at that point, so care must be taken that up until the moment the complete initialization is done no other state is modified.

4c5a7018a3 gfx-shader: Add file watching and dynamic UI updates
Thanks to the workaround in obs::tools, gfx::shader::shader now supports dynamically rebuilding the properties with new properties without crashing OBS Studio. This effectively allows you to have an up to date view of the current parameters for the shader technique.

Additionally with file watching, live development of shaders is possible at very little cost. Currently only file times and size is looked at every 333ms, but in the future it is possible to also watch for file renames and more.

This is a massive improvement to stability and safety when using the plugin, as all exceptions should now no longer be leaked into C controlled code, which can't actually handle exceptions at all.

* Potentially throwing exception during library load.
* Possibly throwing function passed to C.
* Statement does nothing.
* Variable is initialized but not referenced.
* Variable overloads variable in parent scope.

However, all effects must be created either through std::shared_ptr or std::make_shared. If they were not made through one of those means, the code will crash on the ->shared_from_this() call.

7c4d46c1fe gfx/blur/dual-filtering: Implement Dual Filtering Blur
Dual Filtering (or Dual Kawase) is an approximation of Gaussian Blur that can reach much higher Blur sizes at a much lower cost. However it is locked to a 2^n size, which means that currently it isn't possible to use it for blur sizes like 19, 24 and 31.

The Blur works by using the linear sampling of a GPU, combined with down- and upsampling and carefully placed sampling points. This means that there is no need for a linear optimized version of this Blur.

b6d45ce73c gfx/blur/gaussian-linear: Refactor Linear Gaussian Blur
While Gaussian Blur is not a Blur type that really benefits much from linear sampling, it can be used for a slight quality and gpu usage reduction. However for Area and Directional Blur there is a better alternative: Dual Filtering Blur. And as with all other currently implement Linear versions of Blur, only Area and Directional Blur are supported.

This type of Gaussian Blur also has the loading hitch that exists in normal Gaussian Blur.

fedc8e075c gfx/blur/gaussian: Refactor Gaussian Blur
Gaussian Blur is another Blur that now supports the new system, increasing the maxium Blur size to 128 and adding support for Rotational and Zoom blur. Various optimizations were done to the actual shader code which further reduced the GPU usage.

Currently the Gaussian curve is recalculated when the blur is first created, which can lead to a short hitch due to it having to search for the correct kernels. This is currently unavoidable and expected behavior until a better solution is found.
