115 Rather than having the shader source array statically initialised, it is initialised-
116 here instead. This is to allow new shader names to be inserted or existing names moved-
117 around without having to change the order of the glsl strings. It is hoped this will-
118 make future hard-to-find runtime bugs more obvious and generally give more solid code.-
