* However, this can cause a performance decrease on Chrome cmd buffer because
* it 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.
