+*
+*   raylib [shaders] example - Apply an shdrOutline to a texture
+*
+*   NOTE: This example requires raylib OpenGL 3.3 or ES2 versions for shaders support,
+*         OpenGL 1.1 does not support shaders, recompile raylib to OpenGL 3.3 version.
+*
+*   Example originally created with raylib 4.0, last time updated with raylib 4.0
+*
+*   Example contributed by Samuel Skiff (@GoldenThumbs) and reviewed by Ramon Santamaria (@raysan5)
+*
+*   Example licensed under an unmodified zlib/libpng license, which is an OSI-certified,
+*   BSD-like license that allows static linking with closed source software
