First of all, black point compensation is now on by default. This is really rather harmless and only improves the result (where "improvement" means "less black clipping"). Second, this adds an option to limit the ICC profile's contrast, which helps for untagged matrix profiles that are implicitly black scaled even in colorimetric intent. (Note that this relies on BPC being enabled to work properly, which is why the two changes are tied together) Third, this uses the LittleCMS built in black point estimator instead of relying on the presence of accurate A2B tables. This also checks tags and does some amounts of noise elimination. If the option is unspecified and the profile is missing black point information, print a warning instructing the user to set the option, and fall back to 1000 otherwise.
