While GLUT is well-suited to learning OpenGL and developing simple OpenGL applications, GLUT is not a full-featured toolkit so large applications requiring sophisticated user interfaces are better off using native window system toolkits like Motif.
WebAug 27, 2013 · Jimmy Haden. I asked this in the iPhone forum, but thought I'd give it a chance here instead. It seems Unity is setting precision specifiers automatically in GLSL ES shaders with no way of overriding (VERTEX_P as higp, FRAGMENT_P as mediump).

A type qualifier is used in the OpenGL Shading Language (GLSL) to modify the storage or behavior of global and locally defined variables. These qualifiers change particular aspects of the variable, such as where they get their data from and so forth. They come in a number of different categories.
