is everythign else except max-lights the same as the standalone file? May be worth adding a comment also linking to the github file

Yeah I was about to write an explanation for it. It's actually not complete, as I don't know which ones are exactly required and which it's not required in our usage, like I'm sure we won't need MaxLights or 'MaxFragmentUniformComponents' so I set them to zero, but I honestly don't know about MaxCombinedShaderOutputResources. Do you know what exactly we need?

May be worth adding a comment also linking to the github file
