								*   raylib [shaders] example - Apply a shader to some shape or texture
							 | 
						
						
						
							| 
								
							 | 
							
								*
							 | 
						
						
						
							| 
								
							 | 
							
								*   Example complexity rating: [★★☆☆] 2/4
							 | 
						
						
						
							| 
								
							 | 
							
								*
							 | 
						
						
						
							| 
								
							 | 
							
								*   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.
							 | 
						
						
						
							| 
								
							 | 
							
								*
							 | 
						
						
						
							| 
								
							 | 
							
								*   NOTE: Shaders used in this example are #version 330 (OpenGL 3.3), to test this example
							 | 
						
						
						
							| 
								
							 | 
							
								*         on OpenGL ES 2.0 platforms (Android, Raspberry Pi, HTML5), use #version 100 shaders
							 | 
						
						
						
							| 
								
							 | 
							
								*         raylib comes with shaders ready for both versions, check raylib/shaders install folder
							 | 
						
						
						
							| 
								
							 | 
							
								*
							 | 
						
						
						
							| 
								
							 | 
							
								*   Example originally created with raylib 1.7, last time updated with raylib 3.7
