Convert packed 24/32-bit RGB/BGR/RGBA/BGRA input to PAL8 using a per-frame palette whose colors are placed on a face-centered cubic lattice (realized as the scaled D3/D4 checkerboard lattice), with a user-supplied density controlling the number of lattice steps spanning one color axis. Only lattice points actually used by a frame enter its palette; if a frame needs more than 256 of them, the filter will itearatively drop palettte entries and reassign affected pixels until 256 color remain lookup uses the Conway-Sloane rounding algorithm. Supported dithering modes: none, ordered 8x8 bayer (swscale), Cluster & Void blue noise and Floyd-Steinberg error diffusion.
