previous implementation didn't consider multiple canvases,
multiple canvas shared one renderer engine that brought corrupted contexts.
Thus, each canvas instances should have designated renderer engine instances.
Now fixed.
initialization interfaces has been changed for threads count.
if you want to set concrete threads count by system, please specify thread count with it.
std threads:
tvg::Initializer::init(tvg::CanvasEngine::Sw, std:🧵:hardware_concurrency());
if your system provides designed threads info, you can use it.
efl:
tvg_engine_init(TVG_ENGINE_SW, eina_cpu_count());
I recommend to avoid max threads usage for better performance.
