*
* 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)
* 2.0 (08-Nov-2018) Support controls guiLock and custom fonts, reviewed GuiComboBox(), GuiListView()...
* 1.9 (09-Oct-2018) Controls review: GuiGrid(), GuiTextBox(), GuiTextBoxMulti(), GuiValueBox()...
* 1.8 (01-May-2018) Lot of rework and redesign to align with rGuiStyler and rGuiLayout
* 1.5 (21-Jun-2017) Working in an improved styles system
* 1.4 (15-Jun-2017) Rewritten all GUI functions (removed useless ones)
* 1.3 (12-Jun-2017) Redesigned styles system
* 1.1 (01-Jun-2017) Complete review of the library
* 1.0 (07-Jun-2016) Converted to header-only by Ramon Santamaria.
* 0.9 (07-Mar-2016) Reviewed and tested by Albert Martos, Ian Eito, Sergio Martinez and Ramon Santamaria.
* 0.8 (27-Aug-2015) Initial release. Implemented by Kevin Gato, Daniel Nicolás and Ramon Santamaria.
