-- * In this library comboboxes are not limited to being a popup
-- * list of selectable text. Instead it is a abstract concept of
-- * having something that is *selected* or displayed, a popup window
-- * which opens if something needs to be modified and the content
-- * of the popup which causes the *selected* or displayed value to
-- * change or if wanted close the combobox.
-- *
-- * While strange at first handling comboboxes in a abstract way
-- * solves the problem of overloaded window content. For example
-- * changing a color value requires 4 value modifier (slider, property,...)
-- * for RGBA then you need a label and ways to display the current color.
-- * If you want to go fancy you even add rgb and hsv ratio boxes.
-- * While fine for one color if you have a lot of them it because
-- * tedious to look at and quite wasteful in space. You could add
-- * a popup which modifies the color but this does not solve the
-- * fact that it still requires a lot of cluttered space to do.
-- *
-- * In these kind of instance abstract comboboxes are quite handy. All
-- * value modifiers are hidden inside the combobox popup and only
-- * the color is shown if not open. This combines the clarity of the
-- * popup with the ease of use of just using the space for modifiers.
-- *
-- * Other instances are for example time and especially date picker,
-- * which only show the currently activated time/data and hide the
-- * selection logic inside the combobox popup.
