So be it, it's quite easy for plugins to ignore MaxThemeName or allocate
such a string length, say 4*MaxThemeName as long as they mange their own
I did not test how VDR reacts when it is fed with a theme or a skin with
a name longer than 16 (seems those are the only 2 places in VDR where
you use those, on statically allocating the strings holding the theme
and the skin, which you store to and load from setup...

Not necessary to exaggerate with such an hilarious example, you're
getting near to sarcastic and missing the point, let's just take your
short example in a more realistic scenario:
just because there still are plugins having to use skins which are
resolution-dependent, so those names aren't at all that uncommonly long
like your example, yet they try to carry some little useful information.
And still, one of them is already violating the limit (if we do not
consider the file extension). Of course, you might say, take out the
'_', or the 'x', I could answer I'd rather take out some letter out of
"rainbow", and so on, you see what I'm trying to point out, it's hitting
a limit difficult to argue...

Could you at least please, name it?
