+ <code class="function">gl_PrimitiveIDIn</code> is a geometry language input variable that holds
+ the number of primitives processed by the shader since the current set of rendering
+ primitives was started. The first primitive processed by the drawing command is numbered
+ zero and the primitive ID counter is incremented after every individual point, line
+ or triangle primitive is processed. For triangles drawn in point or line mode, the
+ primitive ID counter is incremented only once, even through multiple points or lines
+ may actually be drawn. Restarting a primitive topology using the primitive restart
+ index has no effect on the primitive ID counter.
