Performance tests to display camera preview on Pygame window

Config

OSX : pygame 2.4.0 (SDL 2.26.4, Python 3.8.9) + Picamera2 mock

RPi3 : pygame 2.4.0 (SDL 2.0.14, Python 3.9.2) + Picamera2 connected to HQ camera

Tests

Test performed to monitor the game loop speed (FPS) and camera capture per seconds (CPS).

1. Flip the entire screen (preview same size than screen)

Script: use_flip.py

Cycles	FPS/CPS OSX	FPS/CPS RPi3
20	72/28
200	97/77
400	97/84

2. Update only preview rect (smaller than screen)

Script: use_update.py

Cycles	FPS/CPS OSX	FPS/CPS RPi3
20	75/28
200	95/76
400	98/86

3. Update only preview rect on camera event

Script: use_update_on_event.py

Cycles	FPS/CPS OSX	FPS/CPS RPi3
20	94/24
200	93/78
400	92/91

4. Update only preview rect on camera event using dirty concept

Script: use_update_dirty_on_event.py

Cycles	FPS/CPS OSX	FPS/CPS RPi3
20	95/23
200	91/82
400	90/93
