extract a reusable function to calculate the scroll column in different contexts (can be used for a plain string or a LineGap.t; doesn't matter)

minor adjustment to vertical TextScroll: we shouldn't need to move the cursor to the very line in the visible area, or the ver first line in the visible area, to scroll. We scroll if the cursorLine is some distance close to either edge instead.

pull in new version of brolib-sml so that we can get bug fixes for LineGap.getLineNumberOfIdx, delete the TextWindow structure (which was previously used to get the start line to draw from), and replace previous usages of TextWindow with TextScroll.getStartLine. This enables us to scroll in a way tailored to the reimplemented TextBuilder (which do not wrap lines or characters)

implement smoother horizontal scrolling. If the new column is already visible without changing the previous scroll column, then don't change. If the new scroll column is prior to the old, then scroll backwards; else, scroll forwards.

fix bug when the cursor is on the last column of a horizontally-scrollable line. Before this commit, the last column/character was not visible. Now it is. We fixed this by decrementing the 'howManyColumnsCanWeFit' value in the 'TesxtScroll.getScrollColumn' function by 1. This works because it was an off-by-one error that caused this bug in the first place (we didn't previously count column 0 as visible and taking up space)
