 Pixels above the top of the visible area must be ignored.
-Pixels beyond the bottom of the visible area must either be ignored if scrolling is disabled. If scrolling is enabled (see [[#Scrolling|below]]), such pixels must cause scrolling equivalent to the ceiling of (rows beyond the bottom / cell height), both measured in pixels. For instance, if graphics scrolling is enabled, and cells are 10 pixels tall, and the cursor is on the bottom row when the graphic is emitted, and the graphic is 32 pixels tall, the terminal ought scroll up three rows (10 can be displayed, 32 - 10 = 22, ⌈22 / 10⌉ = 3).
