c03c0a9d76 [subset/cff1] Remove unnecessary remap_sid_t::reset 
The object is initialized automatically.
 2023-06-25 17:13:59 -06:00
Behdad Esfahbod
6ed0d04b69 [subset/cff1] In remap_sid_t::reset(), reset everything 
Previous code wasn't resetting next=0; tests were passing.
It's always called when sidmap is empty. So, redundant,
but keeping as is.

be0cec288b [map] Micro-optimize iteration

so is not slowed down by this change.

fc80d20cb5 [serialize] Only hash at most 128 bytes for object_t 
Optimization. Shouldn't in reality bring down the hash performance.
Byte objects differ in their early bytes anyway.
