// - related: vertical scrolling code doesn't work right because of the presence of horizontal scrollbars, but the addition of a vertical scrollbar can affect t->hpagesize and the addition of a horizontal scrollbar can affect t->pagesize, leading to a catch 22 situation and a potential infinite loop if we just say "repeat the process if one changes"
