pygame

Hijacking top post for tasks:

• Add environment variable to pygame module docs with the other environment variables
• Add note about current behaviour (defaults to no joystick events for apps without focus) to joystick module introduction somewhere.
• Nice to have: open a new issue about adding SetSDLHint() & GetSDLHint() (names not final) to new context module.

**Win

It would be great to be able to screenshot a game, similar to Pygame.

• Suggestion (@lucblassel )
  In algorithms with variants, like Shell Sort, should have a way to the user select an variant to be visualized.
• How it could be implemented:
  Add a Input Box, like a drop list, in front of algorithm selection box.
• Are you up to do it?
  I @LucasPilla will be working on this, feel free to contribute!
