-//NOTE TO TBIRD
-// 1. Each sprite has a Box2D body.  You can look in "rc_sprite2D.h" to see how a sprite is structured.
-// 2. A box2D world is setup for each canvas. So a sprite will be attached to the canvas thats active when its created. When that canvas is destroyed, so is the sprite.
-// 3. By default, I have the sprite.physics_enabled attribute set to false. I feel like it makes sense to have a user intentionally enable physics since a user may not want physics for every sprite.
-// 4. The sprite.visible attribute only determines whether to draw the sprite. The physics simulation will still happen each frame unless physics are disabled.
-// 5. Don't change the value of sprite.active. Its used to check whether a sprite exists or not. I have an array of sprites in rc_sprite2D.h and if the active attribute is set to false, I reuse that slot to create a new sprite. If there is no inactive sprites in the array then I add a new sprite index to the array.
-// 6. The time step, velocity Iterations, and position iterations are part of the canvas.physics2D attribute. You will need to make functions to allow the user to change those.
-// 7. If you want to modify how sprites are rendered then you can just change the drawSprites() function above these notes.
