  24 /** Paragraph 4 of the Errors section:
  25  *
  26  * The error INVALID_OPERATION is generated by EndFragmentShaderATI if
  27  * <argN> passed to ColorFragmentOp[1..3]ATI or
  28  * AlphaFragmentOp[1..3]ATI is PRIMARY_COLOR_ARB or
  29  * SECONDARY_INTERPOLATOR_ATI on the first pass of a two-pass shader,
  30  * or if the shader cannot be compiled due to some other
  31  * implementation-dependent limitation.  EndFragmentShaderATI will
  32  * still have a side-effect if this error is encountered: the
  33  * Begin/EndFragmentShaderATI pair will be closed, and the current
  34  * shader will be undefined.
