Function returning the vertex position in clip space.

/*
  vec3 model_pos = gl_Vertex.xyz;
  vec4 view_pos = gl_ModelViewMatrix * vec4(model_pos, 1.0);
  vec4 clip_pos = gl_ProjectionMatrix * view_pos;
*/

vec4 clip_pos = ftransform(); // Equivalent to the above, not accounting for possible rounding differences.

gl_Position = clip_pos;
