*
* raylib [core] example - Basic window (adapted for HTML5 platform)

* To compile it for PLATFORM_WEB just uncomment #define PLATFORM_WEB at beginning
*
* This example has been created using raylib 1.3 (www.raylib.com)
* raylib is licensed under an unmodified zlib/libpng license (View raylib.h for details)
