+ *   MRB_SYM(xor)    //=> xor    (Word characters)
+ *
+ * For `MRB_OPSYM`, specify the names corresponding to operators (see
+ * `MRuby::Presym::OPERATORS` in `lib/mruby/presym.rb` for the names that
+ * can be specified for it). Other than that, describe only word characters
+ * excluding leading and ending punctuations.
+ *
+ * These macros are expanded to `mrb_intern_lit` if presym is disabled,
+ * therefore the mruby state variable is required. The above macros can be
+ * used when the variable name is `mrb`. If you want to use other variable
+ * names, you need to use macros with `_2` suffix, such as `MRB_SYM_2`.

+/**********************************************************************************************
+*
+*   raymath v1.5 - Math functions to work with Vector2, Vector3, Matrix and Quaternions
+*
+*   CONFIGURATION:
+*
+*   #define RAYMATH_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 RAYMATH_STATIC_INLINE
+*       Define static inline functions code, so #include header suffices for use.
+*       This may use up lots of memory.
+*
+*   CONVENTIONS:
+*
+*     - Functions are always self-contained, no function use another raymath function inside,
+*       required code is directly re-implemented inside
+*     - Functions input parameters are always received by value (2 unavoidable exceptions)
+*     - Functions use always a "result" anmed variable for return
+*     - Functions are always defined inline
+*     - Angles are always in radians (DEG2RAD/RAD2DEG macros provided for convenience)

+*       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.

+*   rgestures - Gestures system, gestures processing based on input events (touch/mouse)
+*
+*   NOTE: Memory footprint of this library is aproximately 128 bytes (global variables)
+*
+*   CONFIGURATION:
+*
+*   #define GESTURES_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

+*
+*   #define GESTURES_STANDALONE
+*       If defined, the library can be used as standalone to process gesture events with
+*       no external dependencies.

+*
+*   rlgl v4.0 - A multi-OpenGL abstraction layer with an immediate-mode style API
+*
+*   An abstraction layer for multiple OpenGL versions (1.1, 2.1, 3.3 Core, 4.3 Core, ES 2.0)
+*   that provides a pseudo-OpenGL 1.1 immediate-mode style API (rlVertex, rlTranslate, rlRotate...)
+*
+*   When chosing an OpenGL backend different than OpenGL 1.1, some internal buffer are
+*   initialized on rlglInit() to accumulate vertex data.
+*
+*   When an internal state change is required all the stored vertex data is renderer in batch,
+*   additioanlly, rlDrawRenderBatchActive() could be called to force flushing of the batch.
+*
+*   Some additional resources are also loaded for convenience, here the complete list:
+*      - Default batch (RLGL.defaultBatch): RenderBatch system to accumulate vertex data
+*      - Default texture (RLGL.defaultTextureId): 1x1 white pixel R8G8B8A8
+*      - Default shader (RLGL.State.defaultShaderId, RLGL.State.defaultShaderLocs)
+*
+*   Internal buffer (and additional resources) must be manually unloaded calling rlglClose().
+*
+*
+*   CONFIGURATION:
+*
+*   #define GRAPHICS_API_OPENGL_11
+*   #define GRAPHICS_API_OPENGL_21
+*   #define GRAPHICS_API_OPENGL_33
+*   #define GRAPHICS_API_OPENGL_43
+*   #define GRAPHICS_API_OPENGL_ES2
+*       Use selected OpenGL graphics backend, should be supported by platform
+*       Those preprocessor defines are only used on rlgl module, if OpenGL version is
+*       required by any other module, use rlGetVersion() to check it
+*
+*   #define RLGL_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 RLGL_RENDER_TEXTURES_HINT
+*       Enable framebuffer objects (fbo) support (enabled by default)
+*       Some GPUs could not support them despite the OpenGL version
+*
+*   #define RLGL_SHOW_GL_DETAILS_INFO
+*       Show OpenGL extensions and capabilities detailed logs on init
+*
+*   #define RLGL_ENABLE_OPENGL_DEBUG_CONTEXT
+*       Enable debug context (only available on OpenGL 4.3)
+*
+*   rlgl capabilities could be customized just defining some internal
+*   values before library inclusion (default values listed):
+*
+*   #define RL_DEFAULT_BATCH_BUFFER_ELEMENTS   8192    // Default internal render batch elements limits
+*   #define RL_DEFAULT_BATCH_BUFFERS              1    // Default number of batch buffers (multi-buffering)
+*   #define RL_DEFAULT_BATCH_DRAWCALLS          256    // Default number of batch draw calls (by state changes: mode, texture)
+*   #define RL_DEFAULT_BATCH_MAX_TEXTURE_UNITS    4    // Maximum number of textures units that can be activated on batch drawing (SetShaderValueTexture())
+*
+*   #define RL_MAX_MATRIX_STACK_SIZE             32    // Maximum size of internal Matrix stack
+*   #define RL_MAX_SHADER_LOCATIONS              32    // Maximum number of shader locations supported
+*   #define RL_CULL_DISTANCE_NEAR              0.01    // Default projection matrix near cull distance
+*   #define RL_CULL_DISTANCE_FAR             1000.0    // Default projection matrix far cull distance
+*
+*   When loading a shader, the following vertex attribute and uniform
+*   location names are tried to be set automatically:
+*
+*   #define RL_DEFAULT_SHADER_ATTRIB_NAME_POSITION     "vertexPosition"    // Binded by default to shader location: 0
+*   #define RL_DEFAULT_SHADER_ATTRIB_NAME_TEXCOORD     "vertexTexCoord"    // Binded by default to shader location: 1
+*   #define RL_DEFAULT_SHADER_ATTRIB_NAME_NORMAL       "vertexNormal"      // Binded by default to shader location: 2
+*   #define RL_DEFAULT_SHADER_ATTRIB_NAME_COLOR        "vertexColor"       // Binded by default to shader location: 3
