SimpleShaderProgramBuilder with DiscardTransparentFragments set throws ShaderCompilationException

Repro Steps:

Create a SimpleShaderProgramBuilder
Set DiscardTransparentFragments to true
Build shader

Expected Results: Shader generate correclty
Actual Results: TrippyGL.ShaderCompilationException: 'FragmentShaderArb didn't compile properly:
0(16) : error C1048: invalid character 'A' in swizzle "A"
'

Cause is in SimpleShaderProgramBuilder.cs line 303, the GLSL code "if (finalColor.A <" is invalid, the A should be lowercase.

NuGet package

Looking into tinkering around with this project a bit, any plans on release a nuget package? Also noticed the project doesn't have any CI testing with Azure DevOps or GitHub Actions.
Should I just use this as a submodule for now?

System.MissingMethodException: Method not found

Hello, today, when i tryed to load Texture2D with Texture2DExtensions, i get a System.MissingMethodException: Method not found

Code to load: texturea = Texture2DExtensions.FromImage(device, SixLabors.ImageSharp.Image.Load<SixLabors.ImageSharp.PixelFormats.Rgba32>("1.jpg"));

Full stacktrace:

Who has a case of combining with Avalonia

I found this case avalonia-silk.net
But loops and 2D drawing are too difficult for me

Fix uniform names on struct arrays

The name of the uniforms isn't properly cut.

This is because of the code at the constructor of ShaderUniform:

TrippyGL/TrippyGL/ShaderUniform.cs

Lines 49 to 60 in 2ef708c

 internal ShaderUniform(ShaderProgram owner, int uniformLoc, string name, int size, UniformType type) 

 { 

 OwnerProgram = owner; 

 UniformLocation = uniformLoc; 

 Size = size; 

 UniformType = type; 

 // The name might come as array name for array uniforms. 

 // We need to turn the name "arrayUniform[0]" into just "arrayUniform" 

 int nameIndexOfThing = name.LastIndexOf('['); 

 Name = nameIndexOfThing > 0 ? name.Substring(0, nameIndexOfThing) : name;
