Compatibility profile on Mac OS

[camplowell]

Compatibility profile is not natively supported on Mac OS. However, both Iris and Optifine feature GLSL transformers that allow shaders to use compatibility profile all the way up to #version 410. On the other hand, core profile is a second class citizen on both shader mods.

I would like to be able to use the language server for shader development, but the lack of compatibility profile support is stopping me from using it to lint my code.

Likely the only solution to this problem would be to either implement or pull a preprocessing program that converts compatibility profile code into core profile, at least well enough for the purposes of linting.
