The Open Toolkit is set of fast, low-level C# bindings for OpenGL, OpenGL ES, OpenAL and OpenCL. It runs on all major platforms and powers hundreds of apps, games and scientific research.  It provides bindings for GLFW windowing, input and a game loop, and is the perfect start for your own game engine.  OpenTK comes with simple and easy to follow tutorials for learning *modern* OpenGL. These are written by the community and represent all of the best practices to get you started.  Learn how to use OpenTK here:  https://opentk.net/learn/index.html  Sample projects that accompany the tutorial can be found here:  https://github.com/opentk/LearnOpenTK  We have a very active discord server, if you need help, want to help, or are just curious, come join us!  https://discord.gg/6HqD48s

Updated all projects to target .net8.0. (@NogginBops)
Removed `MathHelper` functions that just called directly into `Math` and `MathF`. (@BoyBaykiller)
Removed old quake inverse sqrt implementation in `MathHelper.InverseSqrtFast` in favour of `Math(F).ReciprocalSqrtEstimate`. (@BoyBaykiller)
SIMD optimized all MatrixNxM and VectorN equals checks. (@BoyBayKiller, @NogginBops)
Vector2d.SizeInBytes returns 16 instead of 8. (@BoyBayKiller)
Merged latest OpenTK 4.8.3 changes onto 5.0-pre.11. (@NogginBops)
This means that some changes from the upcoming 4.8.3 are also in this release.
See https://github.com/opentk/opentk/pull/1734 for full details.
Some of these changes includes:
Update to GLFW 3.4. (@NogginBops)
Add swizzle matrices and general math fixes. (@NogginBops)
Add `VectorN.Slerp` (spherical interpolation) and `VectorN.Elerp` (exponential interpolation). (@NogginBops)
Unclamp `MathHelper.Lerp` so t outside [0, 1] can be used. (@NogginBops)
[OpenAL fixes.](https://github.com/opentk/opentk/pull/1716) (@NogginBops)
Vulkan bindings changes:**
Added Vulkan API bindings in `OpenTK.Graphics.Vulkan`. Feedback welcome! (@NogginBops)
OpenGL bindings changes:**
Removed all automatic length calculations from the OpenGL bindings. (@NogginBops)

Switch to using `out` by default, and use automatic and manual marking for `in` and `ref`. (@NogginBops)
Only convert `out` parameters to return values if they are the last `out` parameter. This removes some weird overloads. (@NogginBops)
Update to latest gl.xml and wgl.xml, resulting in more up to date API definition. (@NogginBops)
Don't generate return overloads for functions that return more than one item. (@NogginBops)
