Vertex Shaders
Note For testing purposes, you can use a simple pass-through vertex shader:
#version 120
void main(void) {
gl_Position = ftransform();
}

Fragment Shaders
Note To check if your shader is working, add this as the last line, it should turn all pixels black:
gl_FragColor = vec4 (0.0,0.0,0.0,1.0);
