Fix many color correction problems with OpenGL ES
On GLES, check for OES_texture_3D extension for color correction Remove a block of ugly hack code that was supposedly needed to build with OpenGL ES. Convert the lookup texture data to uint8 on OpenGL ES before sending it via glTexImage3D, because uint16 is not supported. Check if the shaders have been reinitialized successfuly when trying to activate color correction, prevent black screens when there are issues with the shaders.
