* Add dithering to gradients * Add support for 8x8 matrix for ordered dithering * Fix CI errors * Try error diffusion on vertical gradient too * Vertical error diffusion dithering * Add support for runtime based dithering mode selection (from none, ordered, error diffusion). * Reduce the binary size of the code by sharing the dithering table when appropriate. * Fix CI * Fix CI * Review corrections * Fix union mapping * Revert bg_color changes * Fix for keeping bg_color in the API. * Fix after review * Add support for setting multiple stops per gradient in the style API * Let's make an example Co-authored-by: Gabor Kiss-Vamosi <kisvegabor@gmail.com>
