Softwrap implementation enhanced to fix various issues with scrolling, centering, relocating etc. The main idea is simple: work not with simple line numbers but with (Line, Row) pairs, where Line is a line number in the buffer and Row is a visual line (a row) number within this line. The logic remains mostly the same, but simple arithmetic operations on line numbers are replaced with corresponding operations on (Line, Row) pairs. Fixes #632, #1657
