     gluDisk - draw a disk


     void gluDisk( GLUquadric* quad,
                   GLdouble inner,
                   GLdouble outer,
                   GLint slices,
                   GLint loops )


     quad    Specifies the quadrics object (created with

     inner   Specifies the inner radius of the disk (may be 0).

     outer   Specifies the outer radius of the disk.

     slices  Specifies the number of subdivisions around the z

     loops   Specifies the number of concentric rings about the
             origin into which the disk is subdivided.


     gluDisk renders a disk on the z = 0 plane. The disk has a
     radius of outer, and contains a concentric circular hole
     with a radius of inner. If inner is 0, then no hole is gen-
     erated. The disk is subdivided around the z axis into slices
     (like pizza slices), and also about the z axis into rings
     (as specified by slices and loops, respectively).

     With respect to orientation, the +z side of the disk is con-
     sidered to be "outside" (see gluQuadricOrientation). This
     means that if the orientation is set to GLU_OUTSIDE, then
     any normals generated point along the +z axis. Otherwise,
     they point along the -z axis.

     If texturing has been turned on (with gluQuadricTexture),
     texture coordinates are generated linearly such that where
     r = outer, the value at (r, 0, 0) is (1, 0.5), at (0, r, 0)
     it is (0.5, 1), at (-r, 0, 0) it is (0, 0.5), and at (0, -r,
     0) it is (0.5, 0).
