Top-down shooter written in Odin & Raylib.

• Get rid of Queedo lib. Just inline everything into the project so it's more flexible and we don't need to jump around projects.
• Implement projectiles:
  • Impact functionality.
  • Projectile collision.
  • Change actor move code to prevent tunneling.
  • Pistol projectile attack for starters.
• Make a particle system.
• Make a sound system.
  • Sounds should be able to attach to actors and play at their position.
  • Some non-positional sounds just play.
  • Probably a fixed sparse array of sounds just like actors: []Actor.
• Add debug drawing stuff to Queedo lib.
• Rework actors from []^Actor to []Actor. Simply have a fixed array of values instead of pointers of heap-allocated actors, so iteration is faster, and we can also completely ditch the whole pooling shabang.
• Add a "scan-line" screen effect.
• Change world units to 1 unit = 1 tile.
• Add a camera and rotation system so that we always head "up".
• Remove the mass-dependent push-away of actors. When an actor tries to move into another actor, it should simply push itself away.
• Currently, diagonal movement against walls has no effect on the other, unblocked axis. We need to do this.
