Color filter sharpening now clamps the output. The sharpening delta is now calculated from the difference of two levels of vertex averaging instead of one smooth iteration and the base color. TODO: Sharpen in a different color space; SRGB-linear has saturation artifacts. I tried HSL but it had value artifacts. I'd like to try LAB but we don't seem to have conversion functions for it (at least as far as I could see).
