Benchmarking shows that this provides a very slighty performance boost when rendering fonts with lots of quadratic bezier arcs, compared to the recursive arc splitting, but only when SSE2 is available, or on 64-bit CPUs. On a 2017 Core i5-7300U CPU on Linux/x86_64: ./ftbench -p -s10 -t5 -cb .../DroidSansFallbackFull.ttf Before: 4.033 us/op (best of 5 runs for all numbers) After: 3.876 us/op ./ftbench -p -s60 -t5 -cb .../DroidSansFallbackFull.ttf Before: 13.467 us/op After: 13.385 us/op
