Subject: Make the default constructor of Resources protected
X-Git-Url: http://git.tdb.fi/?p=libs%2Fdemoscene.git;a=commitdiff_plain;h=08fa4d11a07a52e62eb4e30730d2a2b9cdcb568d;hp=94151737f2983ca7cade5be0e20c98fbc6f11eea

Make the default constructor of Resources protected

... instead of private.  This enables derived classes to call the default
constructor and then add their own types before initializing the sources.
