glIsShader returns GL_TRUE if shader is the name of a shader object previously created with
       glCreateShader() and not yet deleted with glDeleteShader(). If shader is zero or a non-zero value that is
       not the name of a shader object, or if an error occurs, glIsShader returns GL_FALSE.

       glIsShader - Determines if a name corresponds to a shader object

       No error is generated if shader is not a valid shader object name.

       A shader object marked for deletion with glDeleteShader() but still attached to a program object is still
       considered a shader object and glIsShader will return GL_TRUE.

shader
           Specifies a potential shader object.
