set-line-count

Sets the canvas's graphical minimum height to display a particular number of lines of text. The line height is determined by measuring the difference between the top and bottom of a displayed editor's first line. The minimum height is not changed until the canvas gets an editor. When the canvas's editor is changed, the minimum height is recalculated.

If the line count is set to #f, then the canvas's graphical minimum height is restored to its original value.
