/**
* 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).
*
* Since: 1.0
