Add Context to API Docs / More API Use Ideas

[torch2424]

quote from @binji : Here's my idea: try to think of some users of this API, and what the code would be like. A few ideas: a tool that makes an animated gif of the title screen of any game; an AI that can analyze and play tetris; a tool to extract music into an mp3; a game input fuzzer (explores behavior by trying various button combos at different times); etc. I'm sure you can think of plenty more. The point is to see what it would be like to use the API to make these tools, and if the API helps you or gets in your way.
