Exactly. But then there is no need for WriteLine() when we are doing the
initial CalculateHeight() once we've rendered what's in the viewport,
because all the calculations have already been done. Right now, both
GetLineMetrics() and WriteLine() are called for every line in the document
when a new document is opened.

I am not worried about the speed of actual writing to the screen. I am
just worried about the speed of opening a new page.
