I'm not so sure about that. Why should the user have to care about cache sizes 
and the like? This should be something that the implementation takes care of 
transparently and (hopefully) intelligently. Think about it from the user's 
point of view. Would (s)he know how to calculate how much RAM is required to 
cache a wallpaper?

Even if it is eventually decided that this should be user configurable 
(although my vote would be for no), we should at least supply a reasonable 
default especially if an svg wallpaper is specified as the default because it 
can take an unacceptable amount of time to repeatedly render on slow 
machines. This I think is a better solution than the semi-arbitrary hardwired 
value of 8MB which is coded at present.

Kind regards,

Sean
