Behdad Esfahbod	10642b3fbf	Disallow null-enabled offsets to unsized structures... ... ...like UnsizedArrayOf<>. This fixes a class of crasher bugs, mostly with color and AAT tables. We cannot use nullable offsets to varsized data that does not declare min_size, because it's nost safe to use our fixed-size null pool for types that have their size external. So, use non_null'able offsets for these. A further enhancement would be to make use of min_size in Null<> itself. Will try that after.	6 years ago

Behdad Esfahbod	3789c557ca	[dfont] Solve the mystery +2 offset thing! ... Previously, ResourceForkHeader was defined as 30 bytes, having the typeCountM1 as last member. There was a mysterious offset-by-2 in the code, derived from FontTools and JDK code this was ported from. In testing, I observed that typeListZ offset is actually 28. Suggesting that the typeCountM1 does NOT actually belong to ResourceForkHeader, but belongs to the array itself. Adjusting for that resolves the mystery +2 offset hack, so everything is clean and good now. This, concludes my dfont hacking. The code looks great now, and I'm happy to leave it. Fuzzers might disagree though, we will see!	6 years ago

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...
