This fixes the case where the effect vanishes, but we still hold an invalid pointer to a parameter of that effect. With the new code, the effect will not vanish as long as an effect pointer exists.
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.
When copying or re-ordering filters, an occasional crash can be observed due to the rendering not being possible yet. With this, it will simply revert back to the original source instead of crashing.
Fixes the bug that rendering an outline would remove all other effects not directly under the outline, while also improving the rendering speed drastically by only initializing and clearing the rendertarget once instead of for each effect.
This filter allows the use of another source as a mask, allowing complex filter graphs and trippy effects, such as creating a text source with three animated videos, each using a different color channel as the mask.
Fixes#18.
Clang on Windows and Clang on Linux behave differently, and of course GCC on Windows (MinGW) and GCC on Linux do too. This is the point where using either compiler on either platform should successfully compile the project without any issues.
Clang and GCC have a ton of warnings however, which definitely need to be fixed in the near future. Some of them are great warnings, like old C style casts, others are non-sense like suggest brackets.

Automatically updates the long description (hover text) if the Type or Subtype field is changed, allowing for more contextual information about what the selected information does.
This refactors the SDF Effects to use a normal blend function instead of doing the blend in the effect itself, improving quality and reducing problematic sampling issues. In addition to this, the effect files have been cleaned up slightly and renamed to their proper names. Glow and Stroke are now supported, which solves both #2 and #4 in one go.
The caching optimization has also now been implemented, reducing the number of renders for this filter to 1 for each tick.
To further distance the code from having to do too much manually, the graphics context is now available as a managed class. All places that previously used obs_enter_graphics and obs_leave_graphics are now using the new gs::context class instead.
Small performance optimization as this removes the extra texture render that would be done by libobs which we don't actually need as we already have a texture to render to for it.
Rendering happens with cached Geometry that is only updated when necessary, such as when the user changes settings. This optimization was necessary to reduce CPU and GPU usage as we can simply re-use the same geomtry instead of recalculating it.
However, the actual source size was never checked. That meant that when a source changed size through any means, the filter would not update the geomtry accordingly, and the result was a squished or stretched image.
With this, the source size is now checked each tick.
Fixes#48
The number of files in the source directory was a little bit much and just made file naming more complex than it had to be. Therefore all files were moved into subdirectories where it matters.
Filters now reside in source/filters/, Sources in source/sources/, OBS Wrappers in obs/, OBS GS Wrappers in obs/gs/, Transitions will reside in source/transitions, Graphics Helpers will be in gfx/.
