This is a moderately fast two-pass gaussian blur implementation. It downscales the framebuffer by half before applying the gaussian shader, which cuts down rendering time quite considerably. The blur shader takes 3 uniforms as input: the blur radius; whether to blur vertically or horizontally; and a brightness value. The blur radius is treated as an integer in C land to simplify calculations. The vertical parameter is treated as an integer by the shader simply due to Cogl not having proper boolean support in snippets. At last, brightness is also added to avoid needing to use an extra effect to achieve that.
