Pixel-accurate (vertical) list scrolling for touchscreen targets.
Looks much smoother now as you don't scroll by whole lines anymore. Add some functions lcd driver to enable the line based scrolling engine to draw the lines with a pixel-based y-offset. This should also allow for a sensible kinetic scrolling mechanism (still a todo). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@28214 a1c6a512-1295-4272-9138-f99709370657
