Dynamic theme switching #30
Description
So, as it turns out, tgui does allow for dynamic theme switching by setting the default theme with tgui::Theme::setDefault(). The reason why some elements doesn't seems to be updated has been narrowed down to the use of getRenderer().
When a widget calls getRenderer(), the widget will generate it's own renderer copy, decoupling it's theme renderer from the shared theme renderer, making the widget unable to receive update when a theme is updated.
This is confirmed in commit df1979d, as removing the getRenderer calls for some widgets allows those widgets to be updated along the theme.
