Post-processing effects

You can apply post processsing effects onto the screen with one of the following functions:

• bloom_screen
• blur_screen
• brighten_screen
• chromatic_abberation_screen
• contrast_screen
• film_grain_screen
• greyscale_screen
• hue_rotate_screen
• invert_screen
• pixelate_screen
• saturate_screen
• sharpen_screen
• vignette_screen

These effects will be applied to everything that has already been rendered out on the screen, but not anything that was rendered afterwards. This will also create new draw queues.
