> * cairo_debug_reset_static_data:
> *
> * Resets all static data within cairo to its original state,
> * (ie. identical to the state at the time of program invocation). For
> * example, all caches within cairo will be flushed empty.
> *
> * This function is intended to be useful when using memory-checking
> * tools such as valgrind. When valgrind's memcheck analyzes a
> * cairo-using program without a call to cairo_debug_reset_static_data(),
> * it will report all data reachable via cairo's static objects as
> * "still reachable". Calling cairo_debug_reset_static_data() just prior
> * to program termination will make it easier to get squeaky clean
> * reports from valgrind.
> *
> * WARNING: It is only safe to call this function when there are no
> * active cairo objects remaining, (ie. the appropriate destroy
> * functions have been called as necessary). If there are active cairo
> * objects, this call is likely to cause a crash, (eg. an assertion
> * failure due to a hash table being destroyed when non-empty).
