thankyouverycool bf59cd7ca5 LibGUI: Add ControlBoxButton to LibGUI
ControlBoxButton consolidates the paint_event for buttons
used in composite box widgets like ComboBox and SpinBox. Its
button bitmaps are built with create_from_ascii like WindowFrame
and ScrollBar controls, making theming more uniform.
