_t_o_k_e_n expects an integer which is used to mark specific sections in
input data so that when it is returned from the feedback buffer
the data is easier to decipher.

ppppaaaasssssssstttthhhhrrrroooouuuugggghhhh passes a single 16-bit integer through the Geometry Pipeline.
Use it in feedback mode to parse the returned information.
For example, you can use ppppaaaasssssssstttthhhhrrrroooouuuugggghhhh between every pair of points that is
being transformed and clipped by the Geometry Engines. If a point is
clipped out, two ppppaaaasssssssstttthhhhrrrroooouuuugggghhhh tokens appear in a row in the output buffer.

This routine is available only in feedback mode; otherwise it is ignored.
