/*******************************************************************************************
*
*   PropertyListControl v1.0.1 - A custom control that displays a set of properties as a list
*
*   UPDATES: last updated - 10 march 2020 (v1.0.1)
*       v1.0.1 - Made it work with latest raygui version
*              - Added `GuiDMSaveProperties()` for saving properties to a text file
*              - A `GuiDMLoadProperties()` is planed but not implemented yet
*              - Added a section property that can work as a way to group multiple properties
*              - Fixed issue with section not having the correct height
*       v1.0.0 - Initial release
*
*
*   MODULE USAGE:
*       #define GUI_PROPERTY_LIST_IMPLEMENTATION
*       #include "dm_property_list.h"
*
*       INIT: GuiDMProperty props[] = { // initialize a set of properties first
                   PCOLOR(),
                   PINT(),
                   PFLOAT(),
                   ...
              };
*       DRAW: GuiDMPropertyList(bounds, props, sizeof(props)/sizeof(props[0]), ...);
*   
*       
*   NOTE: This module also contains 2 extra controls used internally by the property list
*       - GuiDMValueBox() - a value box that supports displaying float values
*       - GuiDMSpinner() - a `better` GuiSpinner()
