Shadertastic 1.1.0

This release focused on Usability and Face Tracking quality.

The major additions are:

• The Face tracking now renders a pre-rasterized texture on demand, and computes the normals of each point. This allow for faster effects (no more ray-tracing required in the shaders), and also more complicated ones, like dynamic texturing of a face.

• Added a new type of parameter : group, closing PR #19 Thank you to @Piripe for its help on this one!
• Added a if option in the metadata for all the parameters, it allows to write conditional display of some effects. It is especially useful for complex effects, where some parameters are only required in some modes. It also helps to display contextual help in a more digestible manner (i.e. not showing every help text every time)
  Note that this feature is still experimental, but I'm pretty confident it's already working as expected.

Changelog​

Added​

• Face Tracking: preraster mode and precomputed normals
• Dev effects: identity and group_test
• Conditional parameters (experimental)

Changed​

• Face tracking: Better lip and chin refinement
• Rewritten several parts of the code for performance and clarity
• Gaussian blur effect: rewritten for better clarity
• Face Detection reference: darker color for lower lip; add the preraster texture; add param show_eyes_balls
• Face Detection Laser Eyes: using preraster for better performance
• Changed labels of face tracking effects; kept names for backward compatibility
• ONXX: centralized session initialization in onnxmediapipe::SessionsProvider

Fixed​

• FaceTrackingCropShader: Fixed early stop not early enough

This is mostly a bug-fixing version.

Added​

• Source/Image parameters : added _size sub parameter as float2 (#ST-21)

Fixed​

• Fixed displacement map bugging with Linear RGB vs sRGB
• Fix in linux build: requirelibonnxruntime.so.1.23.2instead libonnxruntime.so.1 (PR #24)

Changed​

• Updated INNOSetup to 6.7.1

This version fixes a few corner-case issue with low alpha and low luminance colors in transitions.

It also adds a new filter, the Sobel Filter. Everything looks more interesting with a Sobel filter!

Added

• Added Sobel filter
• Added some dev effects, for debugging (not in the release files)

Changed​

• Burn transition: added smoothing effect

Fixed​

• All the built-in transitions are now fully alpha-aware
• Color parameter: Fixed inaccurate color due to sRGB
• Transition: fixed incorrect alpha blending with partially transparent scenes
• Transition: fixed first frame glitching when a transition auto reloads in dev mode

Happy New Year !

This version brings **a lot** of improvements and rewrites!
The metadata file structure has been changed for better adaptability of the project.
The whole render pipeline has been fully rewritten for the best performance possible.
The face tracking is now much faster, especially with multiple face tracking effects stacked.

Also: We have MacOS support now! I don't have a Mac to test it extensively but the alpha testers say everything works perfectly.

But the biggest change, which opens many possibilities, is the `prev_frame` parameter!

It allows an effect to keep track of what happened before, meaning fun stuff like particle simulation
or recursion effects are now possible!
Right now, I have only a few releasable effects to show, but many, many more are coming soon...

Added
- `prev_frame` parameter (#ST-2)
