It is always necessary to call DestroyMagick() in order to assure 
resources (including those used by logging) are freed. :-)

In Magick++, DestroyMagick() will be automatically called, but it will 
be after main() returns, which is very late given that it is possible 
that the user might have already freed referenced data.

I have started working on improving the log code so that it is 
possible to control it programatically and log.mgk would not be 
required.  There will be APIs provided in order to set default values 
which are then used when InitializeMagick() is called.
