GLSL file extensions

[ema2159]

Similarly to #236, GLSL (OpenGL Shading Language) file extensions are missing, but it's also straightforward to solve. Simply add the following lines to the all-the-icons.el file

    ;; GLSL
    ("\\.glsl$"          all-the-icons-fileicon "opengl"                :face all-the-icons-blue)
    ("\\.vert$"          all-the-icons-fileicon "opengl"                :face all-the-icons-blue)
    ("\\.frag$"          all-the-icons-fileicon "opengl"                :face all-the-icons-blue)
    ("\\.geom$"          all-the-icons-fileicon "opengl"                :face all-the-icons-blue)

I haven't had the time to submit a PR, but you should be able to add it fairly easily.

No thank you. The OpenGL logo does not make a very good icon. It's completely illegible in body text sizes.
Also, AFAIK, there are no commonly used icons representing these file types. The closest I can find is material-extensions/vscode-material-icon-theme#597, which is still an open issue.

Indeed. I just thought that it was better than nothing. Though exploring the available icons, it seems there's one named vertex-shader which could be used with different colors for representing the different shaders.

Coming back to this, what about this solution:

It is close to material-extensions/vscode-material-icon-theme#597 that you mentioned.

I'd accept that if you open a PR :)

Awesome! Here you go #253
