+ /* Combobox Widgets
+ * 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.
