*
* raygui v2.8 - A simple and easy-to-use immediate-mode gui library
*
* DESCRIPTION:
*
* raygui is a tools-dev-focused immediate-mode-gui library based on raylib but also
* available as a standalone library, as long as input and drawing functions are provided.
*
* Controls provided:
*
* # Container/separators Controls
* - WindowBox
* - GroupBox
* - Line
* - Panel
*
* # Basic Controls
* - Label
* - Button
* - LabelButton --> Label
* - ImageButton --> Button
* - ImageButtonEx --> Button
* - Toggle
* - ToggleGroup --> Toggle
* - CheckBox
* - ComboBox
* - DropdownBox
* - TextBox
* - TextBoxMulti
* - ValueBox --> TextBox
* - Spinner --> Button, ValueBox
* - Slider
* - SliderBar --> Slider
* - ProgressBar
* - StatusBar
* - ScrollBar
* - ScrollPanel
* - DummyRec
* - Grid
*
* # Advance Controls
* - ListView
* - ColorPicker --> ColorPanel, ColorBarHue
* - MessageBox --> Window, Label, Button
* - TextInputBox --> Window, Label, TextBox, Button
*
* It also provides a set of functions for styling the controls based on its properties (size, color).
*
* CONFIGURATION:
*
* #define RAYGUI_IMPLEMENTATION
* Generates the implementation of the library into the included file.
* If not defined, the library is in header only mode and can be included in other headers
* or source files without problems. But only ONE file should hold the implementation.
*
* #define RAYGUI_STATIC (defined by default)
* The generated implementation will stay private inside implementation file and all
* internal symbols and functions will only be visible inside that file.
*
* #define RAYGUI_STANDALONE
* Avoid raylib.h header inclusion in this file. Data types defined on raylib are defined
* internally in the library and input management and drawing functions must be provided by
* the user (check library implementation for further details).
*
* #define RAYGUI_SUPPORT_ICONS
* Includes riconsdata.h header defining a set of 128 icons (binary format) to be used on
* multiple controls and following raygui styles
*
*
