No, plutovg is also fast, but if you see blend2D using SIMD, it will be faster

`#include #include "blockingconcurrentqueue.h" using namespace std; using namespace moodycamel; void timeCallback() { system("date -s 2022-03-01"); } int main() { BlockingConcurrentQueue queue; // current time 2022-03-21 int value = 0; queue.wait_dequeue_timed(value,...
