What is it all about?
Allegro is a cross-platform library mainly aimed at video game and multimedia programming. It handles common, low-level tasks such as creating windows, accepting user input, loading data, drawing images, playing sounds, etc. and generally abstracting away the underlying platform. However, Allegro is not a game engine: you are free to design and structure your program as you like.
* Hardware accelerated bitmap and graphical primitive drawing support (via OpenGL or Direct3D) * Audio recording support * Font loading and drawing * Video playback * Abstractions over shaders and low-level polygon drawing
