        Description

        We can accelerate various BufferedImageOps in hardware using fragment shaders when
        the OGL pipeline is enabled. These operations can go anywhere from 2x to 500x
        faster when executed in hardware, and those numbers will continue to improve with
        each new generation of shader-level GPUs.
