###Godot Engine bunny mark
#####there are three interchangable levels:
- first uses VisualServer's canvas items for low-level drawing
- second uses draw_texture to paint directly on screen (on node2d actually)
- third uses sprite nodes
there is a single script that handles all the stuff and convenient buttons to add and remove bunnies
#####test results in i5 2320, hd graphics 2000 (max for 20 fps)
- linux native: visualserver and sprites 5500 - bunnies. draw_texture - 2500 bunnies
- html5 chrome: sprites - 900 bunnies.visualserver - 800 bunnies. draw_texture - 500 bunnies
- html5 firefox: visualserver - 500 bunnies. sprites - 400 bunnies. draw_texture - 300 bunnies
