*
*   CONFIGURATION:
*       #define SUPPORT_CAMERA_SYSTEM       1
*           Camera module is included (rcamera.h) and multiple predefined cameras are available:
*               free, 1st/3rd person, orbital, custom
*
*       #define SUPPORT_GESTURES_SYSTEM     1
*           Gestures module is included (rgestures.h) to support gestures detection: tap, hold, swipe, drag
*
*       #define SUPPORT_MOUSE_GESTURES      1
*           Mouse gestures are directly mapped like touches and processed by gestures system
*
*       #define SUPPORT_BUSY_WAIT_LOOP      1
*           Use busy wait loop for timing sync, if not defined, a high-resolution timer is setup and used
*
*       #define SUPPORT_PARTIALBUSY_WAIT_LOOP 0
*           Use a partial-busy wait loop, in this case frame sleeps for most of the time and runs a busy-wait-loop at the end
*
*       #define SUPPORT_SCREEN_CAPTURE      1
*           Allow automatic screen capture of current screen pressing F12, defined in KeyCallback()
*
*       #define SUPPORT_COMPRESSION_API     1
*           Support CompressData() and DecompressData() functions, those functions use zlib implementation
*           provided by stb_image and stb_image_write libraries, so, those libraries must be enabled on textures module
*           for linkage
*
*       #define SUPPORT_AUTOMATION_EVENTS   1
*           Support automatic events recording and playing, useful for automated testing systems or AI based game playing
*
*   DEPENDENCIES:
*       raymath  - 3D math functionality (Vector2, Vector3, Matrix, Quaternion)
*       camera   - Multiple 3D camera modes (free, orbital, 1st person, 3rd person)
*       gestures - Gestures system for touch-ready devices (or simulated from mouse inputs)
