| Animation | This is an abstract data type describing an animation |
| Bitmap | An abstract base class for all sorts of bitmaps |
| Effect | An Effect is some form of animation happening on the screen |
| Effect_changealpha | A generic class for creating a transition from one alpha value to another within a specified area |

| Packed | Abstract base class for all packed bitmap types |
| Readfd | Class for doing secure, non-blocking, line-buffered reads from any file descriptor |
| RGB | 24-bit RGB bitmap |
