Questions: Adding PHP Graphics Libraries

[mario-deluna]

Hello Everyone,

I've just realized that the "php-collective/awesome-php" repository has been closed, but I see commits by @dereuromark here, so I'm guessing this repository is back to life. :)

I have two questions:

1. I would like to add my own project, php-glfw, to the list. It's not massively popular, but I believe it to be quite unique in the PHP ecosystem. However, I'm not sure which category it might fit into, and I'm also curious if others think it's a reasonable fit for the list at all.
2. For the php-collective repository, I created a bot that checks for old repositories and dead links. If this would be seen as still useful here, I would gladly open a PR.

I wanted to ask here first before I blindly open a PR.

Regards.
