setLiveThumbnail

Sets whether to enable live thumbnail for @self.

When set to TRUE, @self's thumbnail in class@TabOverview will update immediately when @self is redrawn or resized.

If it's set to FALSE, the thumbnail will only be live when the @self is selected, and otherwise it will be static and will only update when method@TabPage.invalidate_thumbnail or method@TabView.invalidate_thumbnails is called.
