.glsl files show up as .c

[Lenny-the-burger]

Describe the bug .glsl, .vert, and .frag (commonly used for opengl shader source files) shows up as a standard .c file.

To Reproduce Steps to reproduce the behavior:

1. Create a file with a .glsl, .vert, or .frag file extension.
2. File icon will show up as a .c file.

Expected behavior Expected a file-specific icon, like the one .hlsl files use (used for DirectX shader source files).
