NAME
       glUseProgramStages - bind stages of a program object to a program
       pipeline

C SPECIFICATION
       void glUseProgramStages(GLuint pipeline, GLbitfield stages,
			       GLuint program);

PARAMETERS
       pipeline
	   Specifies the program pipeline object to which to bind stages from
	   program.

       stages
	   Specifies a set of program stages to bind to the program pipeline
	   object.

       program
	   Specifies the program object containing the shader executables to
	   use in pipeline.

DESCRIPTION
       glUseProgramStages binds executables from a program object associated
       with a specified set of shader stages to the program pipeline object
       given by pipeline.  pipeline specifies the program pipeline object to
       which to bind the executables.  stages contains a logical combination
       of bits indicating the shader stages to use within program with the
       program pipeline object pipeline.  stages must be a logical combination
       of GL_VERTEX_SHADER_BIT, GL_TESS_CONTROL_SHADER_BIT,
       GL_TESS_EVALUATION_SHADER_BIT, GL_GEOMETRY_SHADER_BIT,
       GL_FRAGMENT_SHADER_BIT and GL_COMPUTE_SHADER_BIT. Additionally, the
       special value GL_ALL_SHADER_BITS may be specified to indicate that all
       executables contained in program should be installed in pipeline.

       If program refers to a program object with a valid shader attached for
       an indicated shader stage, glUseProgramStages installs the executable
       code for that stage in the indicated program pipeline object pipeline.
       If program is zero, or refers to a program object with no valid shader
       executable for a given stage, it is as if the pipeline object has no
       programmable stage configured for the indicated shader stages. If
       stages contains bits other than those listed above, and is not equal to
       GL_ALL_SHADER_BITS, an error is generated.

NOTES
       The GL_COMPUTE_SHADER_BIT bit is available only if the GL version is
       4.3 or greater.

ERRORS
       GL_INVALID_VALUE is generated if shaders contains set bits that are not
       recognized, and is not the reserved value GL_ALL_SHADER_BITS.

       GL_INVALID_OPERATION is generated if program refers to a program object
       that was not linked with its GL_PROGRAM_SEPARABLE status set.

       GL_INVALID_OPERATION is generated if program refers to a program object
       that has not been successfully linked.

       GL_INVALID_OPERATION is generated if pipeline is not a name previously
       returned from a call to glGenProgramPipelines() or if such a name has
       been deleted by a call to glDeleteProgramPipelines().
