-*
-*   rcamera - Basic camera system for multiple camera modes
-*
-*   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)
