Make gl_feature_flags_mixin an object instead of a function
In !42314 (comment 414476075) I forgot to call glFeatureFlagsMixin
as a function, which (other than being obviously broken) seems like an easy mistake to make.
If can make the mixin export an object instead as there is no need to call it (I think?)
before:
mixins: [glFeatureFlagsMixin()],
after:
mixins: [glFeatureFlagsMixin],
