scroll engine: Factor out renderer function so it can be called by lcd code.
This is used by lcd_puts_scroll_worker() to render the line immediately
instead of waiting for the next scroll tick when only the text was updated.
Previously lcd_puts_scroll_worker() did not render anything in this case
which could lead to visible blinking.
This fixes blinking scrolling lines with dynamic text in the skin engine.
