-*   External libs:

+*   NOTES:
+*       32bit Colors - Any defined Color is always RGBA (4 byte)
+*       One custom font is loaded by default when InitWindow() [core]
+*       If using OpenGL 3.3 or ES2, one default shader is loaded automatically (internally defined) [rlgl]
+*       If using OpenGL 3.3 or ES2, several vertex buffers (VAO/VBO) are created to manage lines-triangles-quads
 *
-*   Some design decisions:
-*     32bit Colors - All defined color are always RGBA (struct Color is 4 byte)
-*     One custom default font could be loaded automatically when InitWindow() [core]
-*     If using OpenGL 3.3 or ES2, several vertex buffers (VAO/VBO) are created to manage lines-triangles-quads
-*     If using OpenGL 3.3 or ES2, two default shaders could be loaded automatically (internally defined)

-*   Some design decisions:
-*     32bit Colors - All defined color are always RGBA (struct Color is 4 byte)
-*     One custom default font could be loaded automatically when InitWindow() [core]
-*     If using OpenGL 3.3 or ES2, several vertex buffers (VAO/VBO) are created to manage lines-triangles-quads
-*     If using OpenGL 3.3 or ES2, two default shaders could be loaded automatically (internally defined)

-*   Some design decisions:
-*     32bit Colors - All defined color are always RGBA (struct Color is 4 byte)
-*     One custom default font could be loaded automatically when InitWindow() [core]
-*     If using OpenGL 3.3 or ES2, several vertex buffers (VAO/VBO) are created to manage lines-triangles-quads
-*     If using OpenGL 3.3 or ES2, two default shaders could be loaded automatically (internally defined)
