Quad-Ren is a resolution independent 2D graphics engine that aims to ease the development of bitmap-based applications, primarily games. It will run regardless of screen resolution or aspect ratio, and works flawlessly with tiling window managers. It rectifies many of the issues with older methods of 2D game development such as color key transparency (which inevitably leads to aliasing) and having to draw sprites in a specific order, which Quad-Ren handles using alpha transparency and layers respectfully. It is programmed in, and usable from C++, with a simple object-oriented API and a small, well documented, easy to edit code base.
