AA-lib is a low level gfx library just as many other libraries are.
The main difference is that AA-lib does not require graphics device. In
fact, there is no graphical output possible. AA-lib replaces those
old-fashioned output methods with powerful ascii-art renderer. Now my
linux boots with a nice penguin logo at secondary display (yes! Like
Win95 does:) AA-lib API is designed to be similar to other graphics
libraries. Learning a new API would be a piece of cake!
The AA library is needed for GIMP
