Behdad Esfahbod 383060cc33 [ft] Invalidate advance cache if font size changed 2018-09-11 14:41:19 +02:00
Behdad Esfahbod 54998befc4 [ft] Cache advances 
I decided to always use the cache, instead of my previous sketch direction
that was to only allocate and use cache if fast advances are not available.
The cache is a mere 1kb, so just use it...

TODO: Invalidate cache on font size change.
