+- Suggestion from Janos Vegh: the memory-checking classes could
+ also keep return the size of memory currently allocated, with
+ a call to return it e.g. int wxDebugContext::GetMemoryUsed().
+ Maybe even an optional window in debug mode with a tally of memory
+ usage, how many classes of each kind are in use, etc.? That
+ would be neat.

+- In doc/view file selector, document type is selected by
+ extension, not the type selected in the (Windows) file selector.

+- wxArrayDouble class?
