void GLAPIENTRY glScaled( GLdouble x,
                                 GLdouble y,
                                 GLdouble z )
       void GLAPIENTRY glScalef( GLfloat x,
                                 GLfloat y,
                                 GLfloat z )

PARAMETERS
       x, y, z
              Specify scale factors along the x, y, and z axes, respectively.

DESCRIPTION
       glScale produces a nonuniform scaling along the x, y, and z  axes.   The
       three  parameters  indicate  the  desired scale factor along each of the
       three axes.

       The current matrix (see glMatrixMode) is multiplied by  this  scale  ma‐
       trix,  and  the  product  replaces the current matrix as if glScale were
       called with the following matrix as its argument:

                                       x 0 0 0
                                      ⎝0 y 0 0⎠
                                       0 0 z 0
                                       0 0 0 1
       If the matrix mode is either GL_MODELVIEW or GL_PROJECTION, all  objects
       drawn after glScale is called are scaled.

       Use  glPushMatrix and glPopMatrix to save and restore the unscaled coor‐
       dinate system.

NOTES
       If scale factors other than 1 are applied to the  modelview  matrix  and
       lighting is enabled, lighting often appears wrong.  In that case, enable
       automatic normalization of normals by calling glEnable with the argument
       GL_NORMALIZE.

ERRORS
       GL_INVALID_OPERATION is generated if glScale is executed between the ex‐
       ecution of glBegin and the corresponding execution of glEnd.
