Following up on this morning's earlier commits, only invoke the goofy
QScrollArea resizable-plugin-isms if either:
	a.  The plugin is specifically marked as resizable always, or
	b.  The plugin is determined not to fit on the screen

This gives the benefit of making crappy display resolutions or crappy
desktop environments a little more tolerable, while providing the same
experience as before to those who have a modern display...
