A Bob Game Object.
A Bob belongs to a Blitter Game Object. The Blitter is responsible for managing and rendering this object.
A Bob has a position, alpha value and a frame from a texture that it uses to render with. You can also toggle the flipped and visible state of the Bob. The Frame the Bob uses to render can be changed dynamically, but it must be a Frame within the Texture used by the parent Blitter.
Bob positions are relative to the Blitter parent. So if you move the Blitter parent, all Bob children will have their positions impacted by this change as well.
You can manipulate Bob objects directly from your game code, but the creation and destruction of them should be handled via the Blitter parent.
