This program demonstrates using mipmaps for texture maps. To overtly show the effect of mipmaps, each mipmap reduction level has a solidly colored, contrasting texture image. Thus, the quadrilateral which is drawn is drawn with several different colors.

The example is ported from C examples in the OpenGL Programming Guide (known as the "red book").
