Description

The functions stacked-tree-increase-font-height and stacked-tree-decrease-font-height try to increase/decrease the point size of the font in stacked-tree. They add/subtract 1 from the size of the current font, and try to find a font with the new size. If this does not work, they add/subtract 2 and try again. If they find a new font, they set the font in stacked-tree to the new font. The heights of the rectangles are adjusted to fit the new font height.

stacked-tree-increase-font-height and stacked-tree-decrease-font-height are used by the Ctrl-> and Ctrl-< gestures and you can use them to implement your gestures. The &rest ignore means that you can use these functions in the input-model directly.
