Subject: Reintroduce the Resources constructor that immediately loads a file
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=e5da6bc3e1f32342e661893fbb3c1cf873422c2e;p=libs%2Fgltk.git

Reintroduce the Resources constructor that immediately loads a file

This covers many simple use cases and avoids the need of creating a
sub-class to add sources or load data before a Root is created.
