the m->mirror object can never be deleted except in the case of a client
being removed from the owner desk. removing it at any point will break any
users of the deskmirror api and create other issues

sorry - this bug is still there and this tracks references - the
current code DOES NOT DO THIS RIGHT.

and EXACTLY as before p *(mb->m) shows that m is full of garbage.
mb->ec is a garbage pointer, w amd h arte garbage coordinates etc. m
is not tracked. pretty simple. open and close a few windows - mayeb
switch some desktops, THEN restart and see the crashes. its easy
enough to reproduce
if another callback triggered the creation of a deskmirror visual while
the dirty callback was in place, a second mirror object would be created
leading to an orphaned mirror object which retained references to the dm
client and eventually resulting in a crash
this seems to fix an extremely rare issue related to both deskmirror artifacts
and crashes in deskmirror during restart; I was only able to reproduce the crash
twice in the span of over an hour of testing and it seemed to disappear after
this change
This reverts commit 5404adc54f.
I'm strongly against adding refcounts/nullchecks to hide bugs which
are caused by failure to properly track object existence. let's try to avoid
this sort of thing in the future
add deskmirror refs to avoid segv on shutdown/restart due to mb->m
becoming a pointer to freed (now garbage) memory, so trace every
ref/unref and count them to get it right. crash gone!
This reverts commit 5f0506c790.
this commit makes no sense. if it prevents a crash, then there is a more serious bug elsewhere which should not be covered over by this bandaid.
this was a neat experiment, but apparently it's not going to be usable for a long time in anything outside efl/elm
