*
*   raygui v3.5-dev - 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     --> StatusBar, Panel
*       - GroupBox      --> Line
*       - Line
*       - Panel         --> StatusBar
*       - ScrollPanel   --> StatusBar
*
*   # Basic Controls
*       - Label
*       - Button
*       - LabelButton   --> Label
*       - Toggle
*       - ToggleGroup   --> Toggle
*       - CheckBox
*       - ComboBox
*       - DropdownBox
*       - TextBox
*       - TextBoxMulti
*       - ValueBox      --> TextBox
*       - Spinner       --> Button, ValueBox
*       - Slider
*       - SliderBar     --> Slider
*       - ProgressBar
*       - StatusBar
*       - 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).
*
*
*   RAYGUI STYLE (guiStyle):
*
*   raygui uses a global data array for all gui style properties (allocated on data segment by default),
*   when a new style is loaded, it is loaded over the global style... but a default gui style could always be
*   recovered with GuiLoadStyleDefault() function, that overwrites the current style to the default one
*
*   The global style array size is fixed and depends on the number of controls and properties:
*
*       static unsigned int guiStyle[RAYGUI_MAX_CONTROLS*(RAYGUI_MAX_PROPS_BASE + RAYGUI_MAX_PROPS_EXTENDED)];
*
*   guiStyle size is by default: 16*(16 + 8) = 384*4 = 1536 bytes = 1.5 KB
*
*   Note that the first set of BASE properties (by default guiStyle[0..15]) belong to the generic style
*   used for all controls, when any of those base values is set, it is automatically populated to all
*   controls, so, specific control values overwriting generic style should be set after base values.
*
*   After the first BASE set we have the EXTENDED properties (by default guiStyle[16..23]), those
*   properties are actually common to all controls and can not be overwritten individually (like BASE ones)
*   Some of those properties are: TEXT_SIZE, TEXT_SPACING, LINE_COLOR, BACKGROUND_COLOR
*
*   Custom control properties can be defined using the EXTENDED properties for each independent control.
*
*   TOOL: rGuiStyler is a visual tool to customize raygui style.
*
*
*   RAYGUI ICONS (guiIcons):
*
*   raygui could use a global array containing icons data (allocated on data segment by default),
*   a custom icons set could be loaded over this array using GuiLoadIcons(), but loaded icons set
*   must be same RAYGUI_ICON_SIZE and no more than RAYGUI_ICON_MAX_ICONS will be loaded
*
*   Every icon is codified in binary form, using 1 bit per pixel, so, every 16x16 icon
*   requires 8 integers (16*16/32) to be stored in memory.
*
*   When the icon is draw, actually one quad per pixel is drawn if the bit for that pixel is set.
*
*   The global icons array size is fixed and depends on the number of icons and size:
*
*       static unsigned int guiIcons[RAYGUI_ICON_MAX_ICONS*RAYGUI_ICON_DATA_ELEMENTS];
*
*   guiIcons size is by default: 256*(16*16/32) = 2048*4 = 8192 bytes = 8 KB
*
*   TOOL: rGuiIcons is a visual tool to customize raygui icons and create new ones.
*
*
*   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_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_NO_ICONS
*       Avoid including embedded ricons data (256 icons, 16x16 pixels, 1-bit per pixel, 2KB)
*
*   #define RAYGUI_CUSTOM_ICONS
*       Includes custom ricons.h header defining a set of custom icons,
*       this file can be generated using rGuiIcons tool
