    //   type  either GL_VERTEX_SHADER or GL_FRAGMENT_SHADER
    //   str  contents of shader code
    // Returns result of glCreateShader (id of shader)
    //
    // Example:
    //     GLuint vid = compile_shader(GL_VERTEX_SHADER,vertex_shader.c_str());
    //     GLuint fid = compile_shader(GL_FRAGMENT_SHADER,fragment_shader.c_str());

    //     glLinkProgram(prog_id);

    // Known bugs: seems to be duplicate of `load_shader`
