I've left this in because it's in the 0.x recipe - but specs aren't mutually exclusive - in fact a GLES spec won't work without also including egl.

Would be good if we can just remove this option?

@planetmarshall Thanks for packaging this already! However, will this one have support for disabling the debug mode? The current (0.1.36) links gl* functions to glad_debug_gl* instead of glad_gl*. It would be nice if I could disable this behavior (as I have a custom error handler that's a little more useful)

I've disabled the debugging layer by default (as it's normally opt-in anyway).

It can be enabled by specifying the option -o glad/*:debug=True
