// okay ideas for applying themes to GuiComponents:
// 1. ThemeData::applyToImage(component, args)
// NO, BECAUSE:
// - for templated types (TextListComponent) have to include the whole template in a header
// - inconsistent definitions if mixing templated types (some in a .cpp, some in a .h/.inl)
// 2. template<typename T> ThemeData::apply(component, args) with specialized templates
// NO, BECAUSE:
// - doesn't solve the first drawback
// - can't customize arguments for specific types
// 3. GuiComponent::applyTheme(theme, args) - WINNER
// NO, BECAUSE:
// - can't access private members of ThemeData
// - can't this be solved with enough getters?
// - theme->hasElement and theme->getProperty will require 2x as many map lookups (4 vs 2)
// - why not just return a const ThemeElement...
