// Some useful defines to stub out webrender binding functions for when we
// build gecko without webrender. We try to tell the compiler these functions
// are unreachable in that case, but VC++ emits a warning if it finds any
// unreachable functions invoked from destructors. That warning gets turned into
// an error and causes the build to fail. So for wr_* functions called by
// destructors in C++ classes, use WR_DESTRUCTOR_SAFE_FUNC instead, which omits
// the unreachable annotation.
