The package GL.Context
This package lets you query various information about the current OpenGL context:
- Major and minor OpenGL version (since OpenGL 3)
- Version string (legacy for OpenGL 1/2)
- Vendor
- Renderer
- List of supported extensions
- Primary shading language version
- List of supported shading language versions
There is also Has_Extension, which checks whether a given extension
name is part of the extension list (in case when you’re wondering why
the corresponding GLFW function has not been wrapped; this function
provides the same functionality).
