Alpha to coverage demo/test using GL_ARB_multisample OpenGL extension

This demo application allows you to compare the quality between using alpha test and alpha-to-coverage for masked transparency when using multisample antialiasing. The alpha-to-coverage feature is available in the GL_ARB_multisample OpenGL extension and is supported by most hardware that support multisampling and normally produces much better quality for masked textures than alpha test does.
