TokenUtils.getModeAt() is not a cheap method to call, so we need to minimize the number of times it is called. Until we add support for inline css in style attributes, then it's safe to assume that entire line has same mode, so only need to check it once per line. It's simpler to just pass in mode instead of both editor and pos.

Actually, can calculate ignoreNamedColors for line and just pass that in.

@redmunds getModeAt is only called when there is an actual result and it's only called once per line.

Ok. I was hoping to make the loop & params a little cleaner, but that's more efficient, so I'm good with it.
