Actually I was trying to use this approach in the patch because I was afraid that variable line height may need to estimate the whole document height to make scroll work correctly. But during this patching experience I realized that the ktexteditor first line is always a whole line. So the renderer only need to care about the current page instead of whole document, which makes variable line height might not as hard as thought. I won't have time recently to look into the variable line height though.
