Change to polygongraph instead of polygon in roomtool

The polygon room tool used a convoluted process for determining what the
user actually wants to draw. I have changed to the polygon graph
instead, which makes the checks easier and restricts the user a bit
less. In the process however I found a serious problem with my handling
float, so everything needed to change to margin compares (which I of
course should have done in the beginning. Guys, take the warning
seriously and don't ignore it for ten years like I did. It will come
back to haunt you.. apparently) instead of direct equality.
