-*
-* 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.
-*
-* CONTRIBUTORS:
-* Ramon Santamaria: Supervision, review, update and maintenance
-* Marc Palau: Initial implementation (2014)
