*
*   raygui v2.5 - 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 possible
*   to be used 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      --> ListElement
*       - ColorPicker   --> ColorPanel, ColorBarHue
*       - MessageBox    --> Label, Button
*       - TextInputBox  --> 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_RICONS_SUPPORT
*       Includes ricons.h header defining a set of 128 icons (binary format) to be used on
*       multiple controls and following raygui styles
*
*   #define RAYGUI_TEXTBOX_EXTENDED
*       Enables the advance GuiTextBox()/GuiValueBox()/GuiSpinner() implementation with
*       text selection support and text copy/cut/paste support
*
*   VERSIONS HISTORY:
*       2.5 (28-May-2019) Implemented extended GuiTextBox(), GuiValueBox(), GuiSpinner()
*       2.3 (29-Apr-2019) Added rIcons auxiliar library and support for it, multiple controls reviewed
*                         Refactor all controls drawing mechanism to use control state
*       2.2 (05-Feb-2019) Added GuiScrollBar(), GuiScrollPanel(), reviewed GuiListView(), removed Gui*Ex() controls
*       2.1 (26-Dec-2018) Redesign of GuiCheckBox(), GuiComboBox(), GuiDropdownBox(), GuiToggleGroup() > Use combined text string
*                         Complete redesign of style system (breaking change)
