Subject: [PATCH] Ensure that composite/non-composite fonts won't get the same
 `hash` in `PartialEvaluator.preEvaluateFont`

To hopefully help prevent any future bugs, make sure that composite/non-composite fonts cannot accidentally get matching `hash`es. Given the differences between those font types, that's very unlikely to be useful or even correct in general.
