NAME
       glClearColorModeEXT - set gradient clear color mode

C SPECIFICATION
       void glClearColorModeEXT( GLenum pname )

PARAMETERS
       pname  Specifies	 the  symbolic name of a the clear color mode, must be
	      GL_GRADIENT_CLEAR_SOLID_EXT or GL_GRADIENT_CLEAR_LINEAR_Y_EXT.

DESCRIPTION
       The gradient clear extension allows an application to clear a region of
       the color buffer to a gradient color that varies linearly in the verti‐
       cal direction.  The clear color mode determines if a gradient color  or
       a constant color is used to clear the color buffer.

       glClearColorModeEXT  sets the clear color mode specified in pname.  The
       following symbols are accepted for pname:

       GL_GRADIENT_CLEAR_SOLID_EXT
		 The clear value is constant for all pixels in the color  buf‐
		 fer and is set by glClearColor().

       GL_GRADIENT_CLEAR_LINEAR_Y_EXT
		 The  clear  color  uses  GL_GRADIENT_CLEAR_COLOR_TOP_EXT  and
		 GL_GRADIENT_CLEAR_COLOR_BOTTOM_EXT to linearly fill in the  y
		 direction  the	 gradient  colors  for all pixels in the clear
		 region. The top and bottom colors are set with glClearParame‐
		 terEXT.

       NOTES

ERRORS
       GL_INVALID_ENUM	is  generated  if  pname  is  not  one of the accepted
       defined values.
