  * 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_RGBA_8888_PIXEL_OPS_SLOW: Set this to 1 if it is known that performing
- * glReadPixels / glTex(Sub)Image with format=GL_RGBA, type=GL_UNISIGNED_BYTE is
- * significantly slower than format=GL_BGRA, type=GL_UNISIGNED_BYTE.
- *
  * GR_GL_FULL_READPIXELS_FASTER_THAN_PARTIAL: Set this to 1 if calling
  * glReadPixels to read the entire framebuffer is faster than calling it with
  * the same sized rectangle but with a framebuffer bound that is larger than
  * the rectangle read.
  *
  * 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.
