hpnok wants to merge 2 commits into christianpostprivate:master from hpnok:hpnok-perf

👋 following the thread you've posted about how to do faster pixel manipulation here some suggestions on how you can improve your code.

On my somewhat old PC if I run the current build from master i got about 9.7 fps
In a first time I removed duplicated calculations and reduced the amount of dereferencing per frame which nearly doubled my frame rate (17.5 fps)
I then did a quick implementation with surfarray/numpy and got about 80 fps!

I put a switch in the main if you want to compare with and without the surfarray implementation
