  * GR_GL_USE_BUFFER_DATA_NULL_HINT: When specifing new data for a vertex/index
  * buffer that replaces old data Ganesh can give a hint to the driver that the
  * previous data will not be used in future draws like this:
  *  glBufferData(GL_..._BUFFER, size, NULL, usage);       //<--hint, NULL means
  *  glBufferSubData(GL_..._BUFFER, 0, lessThanSize, data) //   old data can't be
  *                                                        //   used again.
  * However, this can be an unoptimization on some platforms, esp. Chrome.
  * Chrome's cmd buffer will create a new allocation and memset the whole thing
  * to zero (for security reasons). Defaults to 1 (enabled).

- * GR_GL_PER_GL_FUNC_CALLBACK: When set to 1 the GrGLInterface object provides
- * a function pointer that is called just before every gl function. The ptr must
- * be valid (i.e. there is no NULL check). However, by default the callback will
- * be set to a function that does nothing. The signature of the function is:
- *    void function(const GrGLInterface*)
- * It is not extern "C".
- * The GrGLInterface field fCallback specifies the function ptr and there is an
- * additional field fCallbackData of type intptr_t for client data.
- *
  * GR_GL_CHECK_ALLOC_WITH_GET_ERROR: If set to 1 this will then glTexImage,
  * glBufferData, glRenderbufferStorage, etc will be checked for errors. This
  * amounts to ensuring the error is GL_NO_ERROR, calling the allocating
  * function, and then checking that the error is still GL_NO_ERROR. When the
  * value is 0 we will assume no error was generated without checking.
  *
  * GR_GL_CHECK_FBO_STATUS_ONCE_PER_FORMAT: We will normally check the FBO status
  * every time we bind a texture or renderbuffer to an FBO. However, in some
  * environments CheckFrameBufferStatus is very expensive. If this is set we will
  * check the first time we use a color format or a combination of color /
