2a878b1b76 [font-funcs] Add two new API

7ba3efa5c6 [tests/fuzzing] Use the correct dirs for subset and repacker fuzzers 2025-02-09 18:42:45 +02:00

4c43fdcd07 [test/fuzzing] Simplify Python scripts further 
We always path the fuzzer path in meson, so we don’t need to search for
fuzzer path in the scripts, and then we can use one script for all the
fuzzers.

be22e43d7d [test/fuzzing] Run each fuzzer on all fonts in one process 
Much much faster, specially under valgrind, than spawning one process per font.
