DESCRIPTION
       gluScaleImage  scales  a  pixel  image using the appropriate pixel store
       modes to unpack data from the source image and pack data into the desti‐
       nation image.

ERRORS
       GLU_INVALID_VALUE is returned if wIn, hIn, wOut, or hOut is negative.

       GLU_INVALID_ENUM is returned if format, typeIn, or typeOut is not legal.

       GLU_INVALID_OPERATION    is   returned   if   typeIn   or   typeOut   is
       GL_UNSIGNED_BYTE_3_3_2 or GL_UNSIGNED_BYTE_2_3_3_REV and format  is  not
       GL_RGB.

       GLU_INVALID_OPERATION    is   returned   if   typeIn   or   typeOut   is
       GL_UNSIGNED_SHORT_5_6_5 or GL_UNSIGNED_SHORT_5_6_5_REV and format is not
       GL_RGB.

       GLU_INVALID_OPERATION    is   returned   if   typeIn   or   typeOut   is
       GL_UNSIGNED_SHORT_4_4_4_4 or GL_UNSIGNED_SHORT_4_4_4_4_REV and format is
       neither GL_RGBA nor GL_BGRA.

       GLU_INVALID_OPERATION    is   returned   if   typeIn   or   typeOut   is
       GL_UNSIGNED_SHORT_5_5_5_1 or GL_UNSIGNED_SHORT_1_5_5_5_REV and format is
       neither GL_RGBA nor GL_BGRA.

       GLU_INVALID_OPERATION    is   returned   if   typeIn   or   typeOut   is
       GL_UNSIGNED_INT_8_8_8_8 or  GL_UNSIGNED_INT_8_8_8_8_REV  and  format  is
       neither GL_RGBA nor GL_BGRA.

       GLU_INVALID_OPERATION    is   returned   if   typeIn   or   typeOut   is
       GL_UNSIGNED_INT_10_10_10_2 or GL_UNSIGNED_INT_2_10_10_10_REV and  format
       is neither GL_RGBA nor GL_BGRA.
