In order for pixelsPerInchChanged to properly rerender things, it seems the (previously-unused) functionality of flushCachedValues is required. So this change puts the functionality of flushCachedValues in flushCache, removes flushCachedValues (no callers in the trunk image), and alters pixelsPerInchChanged for TTCFont to call flushCache instead of recreateCache.
