Pyglet's batch draw different sprites without sfml fast
But pyglet's batch draw the same sprite (each sprite has the same texture) much faster than sfml's draw(sprite)... such as batch draw 10000 sprites.
Can you add a batch draw of the same texture sprite in sfml later? This is faster, on some occasions
#pysmfl example: not full,but you can use c++ sfml to test the speed of draw 10000 same sprite
