Option for a trichromat passthrough method?

[lukehler]

I'm interested in setting up my build script with a method of trichromat (and with all the other methods in place but commented out, perhaps) that just returns the styles completely unchanged. That would allow me to make a single-line configuration change or use an environment variable to quickly check out the results - ideally without having to look up the spelling.

I was going to fork it and add the option, but I thought I'd check first to see if you were interested in adding the feature and/or if you had opinions on the method name.
