glScale(3G)							   glScale(3G)

       glScale,	 glScaled, glScalef - multiply the current matrix by a general
       scaling matrix

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

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

       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
       matrix,	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
       coordinate system.

       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 argu‐
       ment GL_NORMALIZE.

       GL_INVALID_OPERATION is generated if glScale() is executed between  the
       execution of glBegin() and the corresponding execution of glEnd().
