| buffer | The buffer to write the information to. |
| x | The x position. |
| y | The y position. |
返回： N/A（无返回值）
This function will add 2D position data to the vertex currently
being defined for the custom primitive. You supply the buffer to
write the data into as well as the x and y position for
drawing.
vertex_position(buff, x - 100, y - 125);
The above code will set the position of the vertex being defined.
