- _b_u_f_f_e_r expects the buffer into which you want the system to save the
- contents of the names stack. A name is a 16-bit number, that
- you load on the name stack just before you called a drawing
- routine.
-
- _n_u_m_n_a_m_e expects the maximum number of names that you want the system to
- save. This number must not exceed the number of elements in
- _b_u_f_f_e_r.

- ggggsssseeeelllleeeecccctttt turns on the selecting mode. When in selecting mode, the system
- notes when a drawing routine intersects the selecting region and writes
- the contents of the names stack to the specified buffer. If you push a
- name onto the names stack just before you call each drawing routine, you
- can record which drawing routines intersected the selecting region.
-
- Use the current viewing matrix to define the selecting region.
-
- ggggsssseeeelllleeeecccctttt and ppppiiiicccckkkk are identical except ggggsssseeeelllleeeecccctttt allows you to create a
- viewing matrix in selecting mode. To end select mode, call _e_n_d_s_e_l_e_c_t.

- This routine is available only in immediate mode.
-
- In order to select a large point or a wide line in selecting mode, the
- selecting region must intersect the displayed point center or the
- displayed line center respectively. The displayed point center is the
- imaginary point of size 1 specified by the same vertex as the displayed
- point. The displayed line center is the imaginary line of width 1
- specified by the same vertices as the displayed line. In case of a very
- large point or very wide line, you may want to consider drawing a filled
- circle or a filled rectangle respectively instead.
