Ruby bindings for the excellent GLFW library, implemented as a high-performance C extension, using common Ruby idioms and object-oriented API opposed to a direct analog.

This project has several releases on RubyGems, but no release tags on GitHub. Perhaps a quick git push --tags would be a good thing to do?
Use MSYS2's (largely undocumented) built-in support for installing package dependencies simply by specifying them in the gemspec, to fetch the native GLFW binary for Windows users.
Add the few functions that were included with the latest GLFW release.
While GLFW is capable of creating Vulkan contexts, and exposing this functionality would be trivial, using Vulkan with Ruby is rather counter-intuitive and not in high-demand, if any demand at all.
This issue is here simply as a reminder for possible future enhancements or feature requests for this functionality, or even just simply for discussion related to it.
I'm getting an error during gem install glfw:

Any idea what the issue might be? Any help or pointers would be appreciated, thanks!
Bump rake dependency to 12.3.3 due to known security issue with current version.
This security flaw does not effect this project
Add example scripts in the repo showcasing basic functionality using modern OpenGL.
Starting with the next release, version releases will follow the same pattern as the native GLFW library for a more sane way determining which gem version goes with which library version.
Create dummy stubs, with documentation, so that linters can take advantage and use them for code completion, inline documentation, etc. in editors and IDEs.
