Refactorings: Idle Pachinko Camera Bounds

I recently implemented a feature to put bounds on camera movement for the Idle Pachinko game that Matt Torres and I have been developing. When I write code, I typically write it in multiple passes like how an author of a paper or a book takes multiple editing passes over their text. Below is the code for the camera bounds feature in multiple passes, showing how I improved the quality and understandability of the code before opening a pull request and calling it done.
