as far as I have seen any front-end SVN client, all of them let the svn client itself to handle this, so the ".svn" is standardized. (although it does change a bit with svn version, so you may hit a situation where you use for example latest Tortoise, which does use latest SVN, it will convert your working copy and you will be unable to work with it with for example rapidSVN if it is linked to older version of svn lib)
I didn't see any front-end putting anything into .svn related to the front-end.
