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.

Before, the deletion tool was not targeting polygons. I also took the
liberty to broaden the functionality of the surface trait, which now can
check if a rectangle or polygon is contained.

It's still kind of strange to use the polygon tool, but at least it
seems stable enough so I'm confident enough (and sick enough of it) to
release it into the wild.

Previously, the algorithm to check, if a line-segment is inside a
polygon did not have a special case for when the start or end of the
segment is on a polygon corner. In case this corner is reflexive,
checking against one line between this corner and an adjacent one may
not be enough.

The math module was starting to be mostly polygon files and functions,
so those got their own subfolder to make the math module less of a mess.
