• Vector graphics and quadratic curve drawing on the GPU via shaders
• Support for many OpenGL features in an object orientated way, such as framebuffers, shaders, element buffers, and OpenGL state
• Rudimentary support for 2D sprite- or texture-based graphics
• Decent math library
• API similar to XNA
