DESCRIPTION: This file is provide as a standard sample Brew source file.
Please refer to this OpenGL(R)ES brew sample application as a
reference on how to use the standard OpenGL-ES and EGL APIs.
ABSTRACT: The ogles_demo_02 application is a spinning cube that displays
textures on each faces or smooth shading color.
