Hardware and Software 2D Rendering Library

1. Hardware Rendering Technology:

   1.1 OpenGL ES 2.0 + AA Shader: This based on OpenGL ES2 and Its Shading Langauge (GLSL).

   

2. Software Rendering Technology:

   2.1 Agg-Sharp

   Agg-Sharp is the C# port of Anti-Grain Geometry (AGG) version (version 2.4, BSD license)

   This provides 'classic' (pure) software based rendering technology.
