NAME
     fglClearAccum - specify clear values for the accumulation buffer


FORTRAN SPECIFICATION
     SUBROUTINE fglClearAccum( REAL*4 red,
                               REAL*4 green,
                               REAL*4 blue,
                               REAL*4 alpha )


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
     fglClearAccum specifies the red, green, blue, and alpha values used by
     fglClear to clear the accumulation buffer.

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

ERRORS
     GL_INVALID_OPERATION is generated if fglClearAccum is executed between
     the execution of fglBegin and the corresponding execution of fglEnd.

ASSOCIATED GETS
     fglGet with argument GL_ACCUM_CLEAR_VALUE
