// Second main class is the manager which contains a list of quads

// It's usually a good idea to start with the run-time implementation
// because it will impose the most constraints on the data and therefore
// on how the editor should work
//
// Should the runtime lib be a static lib or a DLL?
// It needs to be a DLL if it needs to have global state which is accessible
// across many other DLLs. There are some advantages to having it be a static
// lib, however: for example, some editors, like the particle system, use
// the runtime lib to render the preview. In this case, you want to have it
// be a static lib so that the editor + the game have different notions about
// what data is associated with the particle systems.
