Just to convince myself that this really does still work, I took an
existing app and added the following code to the top of main():
osgDB::Registry::instance()->addFileExtensionAlias( "foo", "osg" );
osg::ref_ptr< osg::Node > testload(
osgDB::readNodeFile( "cow.foo" ) );
Then I renamed cow.osg as cow.foo. Then I set a breakpoint in
ReadFile.cpp at line 1683, and indeed the libraryName comes back as
"osgdb_osgd.dll".
Turns out the file load fails anyway, as the OSG plugin takes one look
at the "foo" extension and returns an error. (This is correct behavior;
the .osg plugin doesn't support the "foo" extension.) But the alias does
get registered and the appropriate plugin does get invoked.
