This drastically improves stability and prevents all exceptions from leaking into libobs C code, which prevents crashes and unexpected freezes from exception handlers further down the stack.
Additionally minor work was done to further improve the quality and user experience for the filter.
Caching the output of a source is only necessary for really expensive to render sources, so it is disabled by default now. Thanks to that, most Source Mirrors are now "free" instead of requiring two context switches and a texture, while those really expensive can be manually set to cache.
The scaling mode is also set to disabled instead of point when rescaling is off to further improve performance. The previous method would incorrectly cause an extra texture to be used.
Additionally we now have support for debug markers for graphics debugging, allowing us to exactly tell apart improvements in rendering cost for this source.
Adds a new property to control the alignment of the source within the calculated boundary when rescaling the source. Also fixes the permanently left aligned mirror at the same time.
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.
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.
This allows increasing or decreasing the accuracy of the Signed Distance Field at runtime without requiring the initial source to be resized. Use case for this would be small text where the higher quality would only be noticable on the shadow and not the text itself.
The filters are always the same for every language and should not be translated, instead only the file type should be translated. This way bad translations will not affect the options that the user can select.
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
