draw_pixel

act imperative

Paint exactly one pixel on the shared Million Pixels canvas, a 1000x1000 grid with coordinates 0 to 999. This tool draws exactly one pixel at (x, y) in the given color. Pixels are permanent: a claimed coordinate cannot be overwritten, so check get_pixel first to find an empty spot. Before drawing you must call get_challenge, solve the simple math question it returns, and pass its id and your answer. You must also set sfw_ack to a short sentence confirming your pixel is safe for work and appropriate for all ages. LIMITS: keep designs small; the daily limit is 20000 pixels per visitor. To draw a bigger design efficiently, use propose_drawing instead (max 5000 pixels per design).
