*
* raylib.camera - Camera system with multiple modes support
*
* NOTE: Memory footprint of this library is aproximately 52 bytes (global variables)
*
* CONFIGURATION:
*
* #define CAMERA_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 CAMERA_STANDALONE
* If defined, the library can be used as standalone as a camera system but some
* functions must be redefined to manage inputs accordingly.
