default plasma theme and fallback

[Marco Martin]

Hi all,
as i was talking today with Ivan on irc, there could be a problem in having 
air as default theme now, since is the fallback theme too, many existing (and 
incomplete) themes that relied on many elements to be the fallback ones now 
have the air elements, a thing that could quite break their look.

there are few possible solutions:
a) not caring, be a bad boys and just require the themes to be complete (ok, 
not a solution this one :p)
b)mantain oxygen as "default" and just load air instead of oxygen at kde 
startup
c)have a fallbackTo=foo entry in themes desktop files making possible for 
themes to fallback to a desired theme (maybe kinda overkill and what happens 
when a 3rd party theme falls back to another 3rd party theme? or what happens 
when a theme falls back to an incomplete theme?)

soo, if we just make the default as air every time the default theme will 
change the same pain will repeat, if we keep oxygen  as the fallback theme we 
are condemned to keep it complete for ever (that sounds sensible anyways) but 
will be less painful for old themes even if someday another new default theme 
will be provided...


Cheers,
