transform-related function names incorrectly marked as lints

[lifeiscontent]

when I do something like this

.arrow {
  @include transform(scaleY(-1));
}

I get this scss-lint error Names of variables, functions, and mixins should be lowercase and not contain underscores. Use hyphens instead.

Not quite a duplicate. The problem here is that scaleY is actually a transform-specific function containing capital letter. We didn't think about this when we created the lint, so it seems like we're going to have to include a whitelist of functions that are allowed within the context of a transform.

I've renamed this issue to correctly describe the problem and have reopened it.
