Load either the vertex or fragment shader from a file.
This function loads a single shader, either vertex or fragment,
identified by the second argument. The source must be a text file
containing a valid shader in GLSL language. GLSL is a C-like language
dedicated to OpenGL shaders; you'll probably need to read a good
documentation for it before writing your own shaders.
