When there were several runs of double width/double height runs with
differing color/rendition/line draw/..., the second and subsequent runs
were positioned wrong. Fix the calculation of the starting x position to
account for double width, and fix a bug were the y position was
incremented for every run instead of for every line.

Can be tested with:
perl -E '$s="\e[0mTEST\e[32mTEST\e[0m"; say "\e#3$s\n\e#4$s"'
