+Subject: [PATCH] placebo: update for new tone mapping desaturation algo
+
+This was introduced in API version 10, and refactors the tone mapping
+desaturation curve into a new, more tunable algorithm that has some
+different behavior. In particular, it allows us to simulate exactly the
+"hollywood" style of tone mapping, so we document those special values
+specifically.
