scroll_engine: Major rework to support pixel-based scrolling and scroll callbacks.
Much of the scrolling work is moved from lcd-bitmap-common to lcd-scroll.c, a small scroll callback routine remains. This callback can potentially be overridden by more extensive scrollers. The callback also gets fed with pixel-based scrolling information, which finally removes the strict line-based nature of the scroll engine. Along with this is the change from scroll_stop_viewport_line() to scroll_stop_viewport_rect() which works on a pixel-based rectangle instead of lines. The ultimate goal is to move most of the scroll work to apps, which can much better decide which line decorations to apply etc. This work is laying the ground work.
