NAME
       glClampColor - specify whether data read via glReadPixels() should be clamped

C SPECIFICATION
       void glClampColor(GLenum target, GLenum clamp);

PARAMETERS
       target
	   Target for color clamping.  target must be GL_CLAMP_READ_COLOR.

       clamp
	   Specifies whether to apply color clamping.  clamp must be GL_TRUE or GL_FALSE.

DESCRIPTION
       glClampColor controls color clamping that is performed during glReadPixels().  target must be GL_CLAMP_READ_COLOR. If clamp is GL_TRUE,
       read color clamping is enabled; if clamp is GL_FALSE, read color clamping is disabled. If clamp is GL_FIXED_ONLY, read color clamping is
       enabled only if the selected read buffer has fixed point components and disabled otherwise.

ERRORS
       GL_INVALID_ENUM is generated if target is not GL_CLAMP_READ_COLOR.

       GL_INVALID_ENUM is generated if clamp is not GL_TRUE or GL_FALSE.

ASSOCIATED GETS
       glGet() with argument GL_CLAMP_READ_COLOR.
