PARAMETERS
       red, green, blue, alpha
                             Specify  the  red,  green,  blue, and alpha values
                             used when the accumulation buffer is cleared.  The
                             initial values are all 0.

DESCRIPTION
       glClearAccum  specifies  the  red, green, blue, and alpha values used by
       glClear to clear the accumulation buffer.

       Values specified by glClearAccum are clamped to the range [-1, 1].

ERRORS
       GL_INVALID_OPERATION is generated if glClearAccum  is  executed  between
       the execution of glBegin and the corresponding execution of glEnd.

ASSOCIATED GETS
       glGet with argument GL_ACCUM_CLEAR_VALUE
