Details:
In multi-page mode, TextEdit sends [horizontalScroller rectForPart:
NSScrollerIncrementLine] to determine the height of the horizontal scroll bar,
for inserting an NSPopUpButton onto the end of it.
All is well, until/unless the window is wide enough that no scroll
buttons/thumb are needed, at which point the button disappears as well.
After some investigation, the reason is that the above call returns zero when
the scroller is not displaying its controls. On OpenStep, and most likely Mac
OS X, the rects do not change just because the controls are not being
displayed.
